Read comparator bits
You read the comparator bits with instructions for digital inputs like
P2_Digin_Long
.
With comparator hold / standard hysteresis, the bits are assigned to the chan-
nels as follows:
The comparator bits for the channel pairs of the free hysteresis are the bits
16…23; the bits are assigned to the channel pairs as follows:
Event input
Channel 16 does also work as event input, so there is no separate pin for this
function. The signal after the comparator is used as event signal.
