BASE_THRESHOLD1
0x0d
1.5.10 BASE_THRESHOLD1
Address = 0x0d
Finger threshold (units: counts) for sensor 1. This threshold is applied when sensor 1 is configured as a button sensor and
automatic threshold mode is disabled. This threshold is also applied when EMC is enabled, as automatic threshold is dis-
abled when EMC is enabled. This threshold is applied as proximity threshold for sensor 1 when it is configured as a proximity
sensor. When sensor 1 is configured as a proximity sensor, the value of this register must be set lower than the value of
PROX_TOUCH_TH1. If this rule is not followed, system behavior is undefined

Bits Name Description
7 : 0 BASE_THRESHOLD1 Finger threshold (units: counts) for sensor 1. This threshold is applied when sensor 1 is config-
ured as a button sensor and automatic threshold mode is disabled. This threshold is also applied
when EMC is enabled, as automatic threshold is disabled when EMC is enabled. This threshold
is applied as proximity threshold for sensor 1 when it is configured as a proximity sensor. When
sensor 1 is configured as a proximity sensor, the value of this register must be set lower than the
value of PROX_TOUCH_TH1. If this rule is not followed, system behavior is undefined. The valid
value of this bit field ranges from 31 to 200.
