2-1 STOP_WRAP R/W 3h
Stop value for one-shot mode. This is the number (between 1-4) of
captures allowed to occur before the CAP(1-4) registers are frozen,
that is, capture sequence is stopped.
Wrap value for continuous mode. This is the number (between 1-4)
of the capture register in which the circular buffer wraps around and
starts again.
Notes: STOP_WRAP is compared to Mod4 counter and, when
equal, 2 actions occur:
- Mod4 counter is stopped (frozen)
- Capture register loads are inhibited
In one-shot mode, further interrupt events are blocked until re-
armed.

3h (R/W) = Stop after Capture Event 4 in one-shot mode
Wrap after Capture Event 4 in continuous mode.
0 CONT_ONESHT R/W 0h
