SENS_SAR1_EN_PAD_FORCE 1: SAR ADC1 pad enable bitmap is controlled by SW, 0: SAR ADC1 pad
enable bitmap is controlled by ULP coprocessor. (R/W)
SENS_SAR1_EN_PAD SAR ADC1 pad enable bitmap; active only when reg_sar1_en_pad_force = 1.
(R/W)
SENS_MEAS1_START_FORCE 1: SAR ADC1 controller (in RTC) is started by SW, 0: SAR ADC1 con-
troller is started by ULP coprocessor. (R/W)
SENS_MEAS1_START_SAR SAR ADC1 controller (in RTC) starts conversion; active only when
reg_meas1_start_force = 1. (R/W)
SENS_MEAS1_DONE_SAR SAR ADC1 conversion-done indication. (RO)

SENS_TOUCH_OUT_1EN 1: wakeup interrupt is generated if SET1 is touched, 0: wakeup interrupt is
generated only if both SET1 & SET2 are touched. (R/W)
SENS_TOUCH_OUT_SEL 1: the touch pad is considered touched when the value of the counter
is greater than the threshold, 0: the touch pad is considered touched when the value of the
counter is less than the threshold. (R/W)
SENS_TOUCH_XPD_WAIT The waiting time (in 8 MHz cycles) between TOUCH_START and
TOUCH_XPD. (R/W)
SENS_TOUCH_MEAS_DELAY The measurement's duration (in 8 MHz cycles). (R/W)
