Note that a proximity condition will be forced enabled if there is a touch condition on any channel. Please refer to Section 6.7 and 6.8 for proximity and touch threshold selections. 8.6 ATI The Automatic Tuning Implementation (ATI) is a sophisticated technology implemented on the new ProxSense® series devices. It allows for optimal performance of the devices for a wide range of sense electrode capacitances, without modification or addition of external components. The ATI allows the tuning of two parameters, an ATI Multiplier and an ATI Compensation, to adjust the Count values for an attached sense electrode. ATI allows the designer to optimize a specific design by adjusting the sensitivity IQS263B Datasheet V1.05 Page 24 of 53 January 2021 IQ Switch® ProxSense® Series and stability of each channel through the adjustment of the ATI parameters. The IQS263B has a full ATI function. The full-ATI function is default enabled, but can be disabled by setting the ATI_OFF bit, or changed to partial or alternative ATI by setting the ATI_Partial and ATI_ALT. The ATI_Busy bit will be set while an ATI event is busy. For more information regarding the ATI algorithm, please contact Azoteq at: ProxSenseSupport@azoteq.com 8.6.1 ATI Sensitivity 8.6.3 ATI Base (Multiplier) The following parameters will influence the base value:  Cs_SIZE1: Size of sampling capacitor.  PROJ_BIAS bits: Adjusts the biasing of some analogue parameters in the mutual capacitive operated IC. (Only applicable in mutual capacitance mode.)  Charge Transfer Frequency  MULTIPLIER bits. The base value used for the ATI function can be implemented in 2 ways: On the IQS263B device, the user can specify the BASE value (Section 6.13) and the TARGET value (Section 6.14) for the proximity channel (CH0) and touch channels (CH1-CH3). 1. ATI_PARTIAL = 0. ATI automatically adjusts MULTIPLIER bits to reach a selected base value2. Please refer to Section 6.13 for available base values. A rough estimation of sensitivity can be calculated as: 2. ATI_PARTIAL = 1. The designer can specify the multiplier settings. These settings will give a custom base value from where the compensation bits will be automatically implemented to reach the required target value. The base value is determined by two sets of multiplier bits. Sensitivity Multipliers which will also scale the compensation to normalise the sensitivity and Compensation Multipliers to adjust the gain. ܵ݁݊‫ ן ݕݐ݅ݒ݅ݐ݅ݏ‬ ܶ‫ܶܧܩܴܣ‬ ‫ܧܵܣܤ‬ As can be seen from this equation, the sensitivity can be increased by either increasing the Target value or decreasing the Base value. It should, however, be noted that a higher sensitivity will yield a higher noise susceptibility. 8.6.2 ATI Target The target value is reached by adjusting the COMPENSATION bits for each channel (ATI target limited to 2048 counts). The target value is written into the respective channel’s TARGET registers. The value written into these registers multiplied by 8 will yield the new target value. (Please refer to Section 6.14) 1 Changing CS_SIZE if ATI_OFF = 0 will change CS Copyright © Azoteq (Pty) Ltd 2019 All rights reserved. 8.6.4 Re-ATI An automatic re-ATI event will occur if the counts are outside its re-ATI limits. The reATI limit or ATI boundary is calculated as the target value divided by 8. For example: - Target = 512, Re-ATI will occur if CS is outside 512±64. 2 ATI function will use user selected CS_SIZE and PROJ_BIAS (if applicable) and will only adjust the MULTIPLIER bits to reach the base values. IQS263B Datasheet V1.05 Page 25 of 53 January 2021 IQ Switch® ProxSense® Series A re-ATI event can also be issued by the host MCU by setting the REDO_ATI bit. The REDO_ATI bit will clear automatically after the ATI event was started. Note: Re-ATI will automatically clear all proximity, touch and halt status bits.

Adjustments of the base values or ATI BANDs are required.

The structure of the control byte is shown in Figure 9.1. 7 bit address MSB 1 0 0 0 I2C Group Figure 9.1 1 0 0 R/W LSB Sub- addresses IQS263B Control Byte. The I2C device has a 7 bit Slave Address (default 0x44H) in the control byte as shown in Figure 9.1. To confirm the address, the software compares the received address with the device address. Sub-address values can be set by OTP programming options. 9.2 I2C Read To read from the device a current address read can be performed. This assumes that the address-command is already setup as desired. Current Address Read Start Control Byte S Figure 9.2 Data n ACK Data n+1 Stop NACK ACK S Current Address Read. If the address-command must first be specified, then a random read must be performed. In this case a WRITE is initially performed to setup the address-command, and then a repeated start is used to initiate the READ section. Start Control Byte S Adr + WRITE Figure 9.3 Random Read Addresscommand ACK ACK Start Control Byte S Adr + READ Data n Stop NACK ACK S Random Read. 9.3 I2C Write To write settings to the device a Data Write is performed. Here the Address-Command is always required, followed by the relevant data bytes to write to the device.

IQS263B Datasheet V1.05 Page 27 of 53 January 2021 IQ Switch® ProxSense® Series 9.4 End of Communication Session / Window Similar to other Azoteq I2C devices, to end the I2C communication session, a STOP command is given. When sending numerous read and write commands in one communication cycle, a repeated start command must be used to stack them together (since a STOP will jump out of the communication window, which is not desired). The STOP will then end the communication, and the IQS263B will return to process a new set of data. Once this is obtained, the communication window will again become available (RDY set LOW). 9.5 I2C Sub-address The IQS263B has four available sub addresses, 44H (default) to 47H, which allows up to four devices on a single I2C bus. 9.5.1 Internal sub-address selection Selecting the sub-address via OTP bits allows the user 4 different options: Table 9.1 I2C sub-address selection FG25 FG26 Device Address 0 0 1 1 0 1 0 1 0x44 0x45 0x46 0x47 9.6 RDY Hand-Shake Routine The master or host MCU has the capability to request a communication window at any time, by pulling the RDY line low. The communication window will open directly following the current conversion cycle. For more details please refer to the communication interface guide. 9.7 I2C Specific Commands bit. A reset will typically take place if a timeout during communication occurs. 9.7.2 I2C Timeout If no communication is initiated from the master/host MCU within the first tCOMMS (tCOMMS = 5.12ms default) of the RDY line indicating that data is available (i.e. RDY = low), the device will resume with the next cycle of charge transfers and the data from the previous conversions will be lost. The timeout time is adjustable in steps of 1.28ms in the Thresholds register (0x0A; byte 7). There is also a timeout (tI2C) that cannot be disabled, for when communication has started but not been completed, for example when the bus is being held by another device. tI2C = 150ms. 9.8 I2C I/O Characteristics The IQS263B requires the input voltages given in Table 9.2, for detecting high (“1”) and low (“0”) input conditions on the I2C communication lines (SDA, SCL and RDY). Table 9.2 IQS263B I2C Input voltage 9.7.1 Show Reset After start-up, and after every reset event, the “Show Reset” flag will be set in the System Flags register (0x01H; byte 0). The “Show Reset” bit can be read to determine whether a reset has occurred on the device (it is recommended to be continuously monitored). This bit will be set ’1’ after a reset. Input Voltage (V) VinLOW VinHIGH 0.3*VDDHI 0.7*VDDHI Table 9.3 provides the output voltage levels of the IQS263B device during I2C communication. The SHOW_RESET bit will be cleared (set to ’0’) by writing a ’0’ into the “Show Reset” Copyright © Azoteq (Pty) Ltd 2019 All rights reserved. IQS263B Datasheet V1.05 Page 28 of 53 January 2021 IQ Switch® ProxSense® Series Table 9.3 IQS263B I2C Output voltage between bits 8 and 9 when any device on the bus is addressed in order to determine whether the clocked address matches its own. This will only occur during times when the IQS263B is monitoring the I2C bus, this is whenever the ready line is low in both streaming and event mode. In event mode, there are also times during the operating cycle where the IQS263B will monitor the I2C bus, regardless of whether an event has occurred, said clock stretching will also take place during these times. It is recommended to place any slave devices which cannot tolerate such behavior on a separate bus. Output Voltage (V) VoutLOW VoutHIGH GND +0.2 (max.) VDDHI – 0.2 (min.) 9.9 Multi -Slave Bus Operation The IQS263B can operate on an I2C bus with other slave devices.
