Detail Description
A hardware reset (by asserting XRST) should be
performed before starting any operation.
Sensor Gain Settings
The sensor gain can be adjusted by varying the number
of capacitors and integration time slot of the sensor
manually through the following registers.

Sensor ADC Output Registers
To obtain sensor ADC value, ‘01’ Hex must be written to
CTRL register. Then, read the value from CTRL register. If
value is 00H, can read sensor output from data register.

Setup Value for Number of Integration Time Slot
The following value can be written to each of the integra-
tion time registers to adjust the gain of the sensor. The
default value after reset for these registers is 00H. These
registers control the number of integration time selected
for each channel. The integration time slot can be varied
from 00H to FFFH. More integration time slot will give
higher sensitivity.
Setup Value for Number of Capacitor
The following value can be written to each of the
capacitor registers to adjust the gain of the sensor. The
default value after reset for these registers is 0FH. These
registers control the number of capacitors selected for
each channel. The maximum selectable capacitor is
16 with the registers starting from 0 (i.e. 0 to 15). Less
capacitor will give higher sensitivity.
