EZ-OTG is designed to easily interface to most high-performance CPUs to add USB host functionality. EZ-OTG has its own 16-bit RISC processor to act as a coprocessor or operate in standalone mode. EZ-OTG also has a programmable IO interface block allowing a wide range of interface options. Interrupts EZ-OTG provides 128 interrupt vectors. The first 48 vectors are hardware interrupts and the following 80 vectors are software interrupts. General Timers and Watchdog Timer EZ-OTG has two built-in programmable timers and a watchdog timer. All three timers can generate an interrupt to the EZ-OTG. Power Management EZ-OTG has one main power-saving mode, Sleep. Sleep mode pauses all operations and provides the lowest power state. Processor Core Functional Overview An overview of the processor core components are presented in this section. Processor EZ-OTG has a general purpose 16-bit embedded RISC processor that runs at 48 MHz. Clocking EZ-OTG requires a 12 MHz source for clocking. Either an external crystal or TTL-level oscillator may be used. EZ-OTG has an internal PLL that produces a 48 MHz internal clock from the 12 MHz source. Memory EZ-OTG has a built-in 4K × 16 masked ROM and an 8K × 16 internal RAM. The masked ROM contains the EZ-OTG BIOS. The internal RAM can be used for program code or data. Table 1.

In Host mode, EZ-OTG supports two downstream ports; each supports control, interrupt, bulk, and isochronous transfers. In Peripheral mode, EZ-OTG supports one peripheral port with eight endpoints for each of the two SIEs. Endpoint 0 is dedicated as the control endpoint and only supports control transfers. Endpoints 1 though 7 support Interrupt, bulk (up to 64 bytes per packet), or isochronous transfers (up to 1023 bytes per packet size). EZ-OTG also supports a combination of Host and Peripheral ports simultaneously, as shown in Table 2. Table 2.

The HPI interface provides DMA access to the EZ-OTG internal memory by an external host, plus a bidirectional mailbox register for supporting high-level communication protocols. This port is designed to be the primary high-speed connection to a host processor. Complete control of EZ-OTG can be accomplished through this interface via an extensible API and communication protocol. Other than the hardware communication protocols, a host processor has identical control over EZ-Host whether connecting to the HPI or HSS port. The HPI interface is exposed through GPIO pins. Note It should be noted that for up to 3 ms after BIOS starts executing, GPIO[24:19] and GPIO[15:8] will be driven as outputs for a test mode. If these pins need to be used as inputs, a series resistor is required (10 ohm to 48 ohm is recommended). Refer to BIOS documentation for addition details. See section “Reset Pin” on page 9.

The mode it boots into is determined by the TTL voltage level of GPIO[31:30] at the time nRESET is deasserted. Table 14 shows the different boot pin combinations possible. After a reset pin event occurs, the BIOS bootup procedure executes for up to 3 ms. GPIO[31:30] are sampled by the BIOS during bootup only. After bootup these pins are available to the application as GPIOs.

Coprocessor Mode EZ-OTG can act as a coprocessor to an external host processor. In this mode, an external host processor drives EZ-OTG and is the main processor rather then EZ-OTG’s own 16-bit internal CPU. An external host processor may interface to EZ-OTG through one of the following three interfaces in coprocessor mode: • HPI mode, a 16-bit parallel interface with up to 16 MBytes transfer rate • HSS mode, a serial interface with up to 2M baud transfer rate • SPI mode, a serial interface with up to 2 Mbits/s transfer rate. At bootup GPIO[31:30] determine which of these three interfaces are used for coprocessor mode. Refer to Table 14 for details. Bootloading begins from the selected interface after POR + 3 ms of BIOS bootup. Standalone Mode In standalone mode, there is no external processor connected to EZ-OTG. Instead, EZ-OTG’s own internal 16-bit CPU is the main processor and firmware is typically downloaded from an EEPROM. Optionally, firmware may also be downloaded via USB. Refer to Table 14 for booting into standalone mode. After booting into standalone mode (GPIO[31:30] = ‘11’), the following pins are affected: • GPIO[31:30] are configured as output pins to examine the EEPROM contents. • GPIO[28:27] are enabled for debug UART mode. • GPIO[29] is configured as OTGID for OTG applications on PORT1A. — If OTGID is logic 1 then PORT1A (OTG) is configured as a USB peripheral. — If OTGID is logic 0 then PORT1A (OTG) is configured as a USB host. • Ports 1B, 2A, and 2B default as USB peripheral ports. • All other pins remain INPUT pins. GPIO[31:30] must be pulled high or low, as needed, using resistors tied to VCC or GND with resistor values between 5K ohm and 15K ohm. GPIO[31:30] must not be tied directly to VCC or GND. Note that in Standalone mode, the pull ups on those two pins are used for the serial I2C EEPROM (if implemented). The resistors used for these pull ups must conform to the serial EEPROM manufacturer's requirements. If any mode other then standalone is chosen, EZ-OTG will be in coprocessor mode. The device will power up with the appropriate communication interface enabled according to its boot pins and wait idle until a coprocessor communicates with it. See the BIOS documentation for greater detail on the boot process.

Power Savings Mode Description EZ-OTG has one main power savings mode, Sleep. For detailed information on Sleep mode; See section “Sleep”. Sleep mode is used for USB applications to support USB suspend and non USB applications as the main chip power down mode. In addition, EZ-OTG is capable of slowing down the CPU clock speed through the CPU Speed register [0xC008] without affecting other peripheral timing. Reducing the CPU clock speed from 48 MHz to 24 MHz reduces the overall current draw by around 8 mA while reducing it from 48 MHz to 3 MHz reduces the overall current draw by approximately 15 mA. Sleep Sleep mode is the main chip power down mode and is also used for USB suspend. Sleep mode is entered by setting the Sleep Enable (bit 1) of the Power Control register [0xC00A]. During Sleep mode (USB Suspend) the following events and states are true: • GPIO pins maintain their configuration during sleep (in suspend). • External Memory Address pins are driven low. • XTALOUT is turned off. • Internal PLL is turned off. • Firmware must disable the charge pump (OTG Control register [0xC098]) causing OTGVBUS to drop below 0.2V. Otherwise OTGVBUS will only drop to VCC – (2 schottky diode drops). • Booster circuit is turned off. • USB transceivers is turned off. • CPU suspends until a programmable wakeup event.

These may also be used as remote wakeup options for USB applications. See section “Power Control Register [0xC00A] [R/W]” on page 13. Upon wakeup, code begins executing within 200 ms, the time it takes the PLL to stabilize.

For more information on the reserved lower memory or the BIOS ROM, refer to the Programmers documentation and the BIOS documentation. During development with the EZ-OTG toolset, the lower area of User's space (0x04A4 to 0x1000) should be left available to load the GDB stub. The GDB stub is required to allow the toolset debug access into EZ-OTG. Figure 6.

A typical application might utilize a 12-ms power-on-reset event = ~7 ms + ~5 ms, respectively. Reset Pin The Reset pin is active low and requires a minimum pulse duration of sixteen 12-MHz clock cycles (1.3 ms). A reset event restores all registers to their default POR settings. Code execution then begins 200 ms later at 0xFF00 with an immediate jump to 0xE000, the start of BIOS. Note It should be noted that for up to 3 ms after BIOS starts executing, GPIO[24:19] and GPIO[15:8] will be driven as outputs for a test mode. If these pins need to be used as inputs, a series resistor is required (10 ohm to 48 ohm is recommended). Refer to BIOS documentation for addition details. USB Reset A USB Reset affects registers 0xC090 and 0xC0B0, all other registers remain unchanged. Memory Map Memory map information is presented in this section. Mapping The EZ-OTG has just over 24 KB of addressable memory mapped from 0x0000 to 0xFFFF. This 24 KB contains both program and data space and is byte addressable. Figure 6. shows the various memory region address locations. Internal Memory Of the internal memory, 15 KB is allocated for user’s program and data code.

HSS Block Mode Transmit BT HSS_TxD t GAP BLOCK mode transmit timing is similar to BYTE mode, except the STOP bit time is controlled by the HSS_GAP value. The BLOCK mode STOP bit time, tGAP = (HSS_GAP – 9) BT, where BT is the bit time, and HSS_GAP is the content of the HSS Transmit Gap register 90xC074]. The default tGAP is 2 BT.

T = 1/48 MHz. When RTS/CTS hardware handshake is enabled, transmission can be held off by deasserting HSS_CTS at least 1.5T before HSS_RTS. Transmission resumes when HSS_CTS returns HIGH. HSS_CTS must remain HIGH until START bit. HSS_RTS is deasserted in the third data bit time. An application may choose to hold HSS_CTS until HSS_RTS is deasserted, which always occurs after the START bit.
