Event Action B
These bits define what action the counter will take upon certain event conditions.
| Value | Name | Description |
|---|---|---|
| 0x0 | NONE | No action |
| 0x1 | - | Reserved |
| 0x2 | - | Reserved |
| 0x3 | UPDOWN | Counts the prescaled clock cycles or counts the matching events according to the setting for event input A. The event signal controls the count direction, up when low and down when high. The direction is latched when the counter counts. |
| 0x4 | RESTART_POSEDGE | Restart counter on positive event edge |
| 0x5 | RESTART_ANYEDGE | Restart counter on any event edge |
| 0x6 | RESTART_HIGHLVL | Restart counter while the event signal is high |

Enable Counter Event Input B
| Value | Description |
|---|---|
| 0 | Counter Event input B is disabled |
| 1 | Counter Event input B is enabled according to EVACTB bit field |
