Timer Interface Module B (TIMB)
Advance Information
332
NOTE:
NOTE:
Before enabling a TIMB channel register for input capture operation,
make sure that the PTFx/TBCHx pin is stable for at least two bus clocks.
TOVx — Toggle-On-Overflow Bit
When TOVx is set, a TIMB counter overflow takes precedence over a
channel x output compare if both occur at the same time.
MSxB:MSxA
Freescale Semiconductor, Inc.
When channel x is an output compare channel, this read/write bit
controls the behavior of the channel x output when the TIMB counter
overflows. When channel x is an input capture channel, TOVx has no
effect. Reset clears the TOVx bit.
For More Information On This Product,
1 = Channel x pin toggles on TIMB counter overflow.
0 = Channel x pin does not toggle on TIMB counter overflow.
