UART_TXD and UART_RXD transfer data between the two devices. The remaining two signals, UART_CTS and UART_RTS, can be used to implement RS232 hardware flow control where both are active low indicators. 3.1.1 UART Setting User can change data format the following selection using PSKEY. However, host shall communicate with default setting UART connection initiated at first time.

No external USB transceiver is required. The device operates as a USB peripheral, responding to requests from a master host controller such as a PC. Both the OHCI and the UHCI standards art supported. The set of USB endpoints implemented can behave as specified in the USB section of the Bluetooth specification v1.2 or alternatively can appear as a set of endpoints appropriate to USB audio devices such as a set of USB speakers. Since USB is a master/slave oriented system (in common with other USB peripherals), This Module only supports USB slave operation. 3.3 SPI (Serial Peripheral Interface) BlueCore3-Multimedia External uses 16-bit data and 16-bit address serial peripheral interface, where transactions may occur when the internal processor is running or is stopped. The BlueCore3-Multimedia External is the slave and receives commands on SPI_MOSI and outputs data on SPI_MISO. 1 2 3 4 5 Reset the SPI interface Write the command word Write the address Write or read data words Termination Hold SPI_CSB high for two SPI_CLK cycles Take SPI_CSB low and clock in the 8 bit command Clock in the 16-bit address word Clock in or out 16-bit data word(s) Take SPI_CSB high 3.4 Kalimba DSP The Kalimba DSP is an open platform Kalimba DSP allowing signal processing functions to be performed on over-air data or CODEC data in order to enhance audio applications. www.hanamciron.co.kr 13 page / 17 pages HBM1X1M Bluetooth V1.2 Class 1 Module Data Book The key features of the DSP include: 32MIPS performance, 24-bit fixed point DSP Core Single cycle MAC of 24 x 24-bit multiply and 56-bit accumulate 32-bit instruction word Separate program memory and dual data memory, allowing an ALU operation and up to two memory accesses in a single cycle Zero overhead looping and branching Zero overhead circular buffer indexing Single cycle barrel shifter with up to 56-bit input and 24-bit output Multiple cycle divide (performed in the background) Bit reversed addressing Orthogonal instruction set Low overhead interrupt 3.5 Audio Interface The audio interface circuit consists of a stereo audio CODEC, dual audio inputs and outputs, and a PCM, I2S or SPDIF configurable interface.

Through its PCM interface, this module has hardware support for continual transmission and reception of PCM data, so reducing processor overhead for wireless headset applications. This module offers a bi-directional digital audio interface that route directly into the baseband layer of the on-chip firmware. It dose not pass through the HCI protocol layer. Hardware allows the data to be sent to and received from a SCO connection This module interfaces directly to PCM audio devices including the following : - Qualcomm MSM 3000 series and MSM 5000 series CDMA baseband devices - OKI MSM7705 for channel A-law and u-law CODEC - Motorola MC145481 8-bit A-law and u-law CODEC - Motorola MC145483 13-bit linear CODEC - STW 5093 and 5094 14-bit linear CODECs 3.7.1 PCM Configuration The PCM configuration is set using two PS keys, PSKEY_PCM_CONFIG32 and PSKEY_PCM_LOW_JITTER_CONFIG.
