Timer Interface Module A (TIMA)
Technical Data
466
NOTE:
NOTE:
Before enabling a TIMA channel register for input capture operation,
make sure that the PTEx/TACHx pin or PTFx/TACHx pin is stable for at
least two bus clocks.
TOVx — Toggle-On-Overflow Bit
When TOVx is set, a TIMA counter overflow takes precedence over a
channel x output compare if both occur at the same time.
MSxB:MSxA
When channel x is an output compare channel, this read/write bit
controls the behavior of the channel x output when the TIMA counter
overflows. When channel x is an input capture channel, TOVx has no
effect. Reset clears the TOVx bit.
1 = Channel x pin toggles on TIMA counter overflow.
0 = Channel x pin does not toggle on TIMA counter overflow.
