Set this bit to turn on the threshold functionality which starts the sampling of channel conversions for
comparison against the threshold value.
Enable this bit to cause the battery charger to shut off (HW_POWER_CHARGE_PWD_BATTCHRG will be
asserted) when the threshold event first asserts (edge triggers the PWD_BATTCHRG). Note: It is the
responsibility of software to ensure that the proper channels are programmed and selected so the
external battery temperature is being monitored by this threshold unit.
This field selects which of the 8 virtual channels this threshold applies to.

This is the threshold value to compare to the selected channel's result value. If oversampling (ACCUMULATE
mode) is selected for the successive sample conversion in each virtual channel, Software is responsible for
setting this value by multiplying NUM_SAMPLES.
