TOVx — Toggle On Overflow Bit
CHxMAX — Channel x Maximum Duty Cycle Bit
Freescale Semiconductor
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 logic 1, setting the CHxMAX bit forces the duty cycle of buffered and
unbuffered PWM signals to 100%. As
after it is set or 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.

Before enabling a TIM channel register for input capture operation, make
sure that the PTD/TCHx pin is stable for at least two bus clocks.
When TOVx is set, a TIM counter overflow takes precedence over a
channel x output compare if both occur at the same time.
