NOTE:
NOTE:
TOVx — Toggle-On-Overflow Bit
When TOVx is set, a TIM counter overflow takes precedence over a
channel x output compare if both occur at the same time.
Reading the high byte of the timer channel x registers (TCHxH) prevents
the channel x pin from toggling until the low byte (TCHxL) is read.
CHxMAX — Channel x Maximum Duty Cycle Bit
CHxMAX
TCHx
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 0, setting the CHxMAX bit forces the
duty cycle of buffered and unbuffered PWM signals to 100%. As

set or cleared. The output stays at the 100% duty cycle level until the
cycle after CHxMAX is cleared.
