Configuration
Low Power Configuration is achieved through setting two values; the Idle Timeout Period and the Sleep Cycle Duration. This
functionality is described in the following section.
5.3.1
Low Power Configuration Register
The Low Power Configuration register is used to set both the Idle Timeout Period and Sleep Cycle Duration multiplication factors.
The I2C slave address of the Low Power Configuration Register is 0x08.

ITP
Idle Timeout Period – The Idle Timeout Period selects the amount to multiply the
TASP (touch acquisition sample period) by to determine the idle interface timeout
(IIT) period of the sensor controller.
000 Encoding 0 – Disables Low Power Mode
001 Encoding 1 – Sets the ITP multiplication factor to 1
~
111 Encoding 7 – Sets the ITP multiplication factor to 7
4:0
SCD
Sleep Cycle Duration – The Sleep Cycle Duration Field selects the amount to
multiply the TASP (touch acquisition sample period) by to determine the Sleep
period of the sensor controller.
00000 Encoding 0 – Disables Low Power Mode
00001 Encoding 1 – Sets the SCD multiplication factor to 1
~
11111 Encoding 31 – Sets the SCD multiplication factor to 31
