Timer Interface Module (TIM)
TOVx — Toggle-On-Overflow Bit
CHxMAX — Channel x Maximum Duty Cycle Bit
94
When channel x is an output compare channel, this read/write bit controls the behavior of the channel x
output when the TIM counter overflows. When channel x is an input capture channel, TOVx has no
effect. Reset clears the TOVx bit.
When the TOVx bit is at one, setting the CHxMAX bit forces the duty cycle of buffered and unbuffered
PWM signals to 100%. As
cleared. The output stays at the 100% duty cycle level until the cycle after CHxMAX is cleared.
1 = Channel x pin toggles on TIM counter overflow.
0 = Channel x pin does not toggle on TIM counter overflow.
When TOVx is set, a TIM counter overflow takes precedence over a
channel x output compare if both occur at the same time.
