CHxMAX — Channel x Maximum Duty Cycle Bit
17.8.5 TIM1 Channel Registers
These read/write registers contain the captured TIM1 counter value of the input capture function or the
output compare value of the output compare function. The state of the TIM1 channel registers after reset
is unknown.
In input capture mode (MSxB:MSxA = 0:0), reading the high byte of the TIM1 channel x registers
(T1CHxH) inhibits input captures until the low byte (T1CHxL) is read.
In output compare mode (MSxB:MSxA ≠ 0:0), writing to the high byte of the TIM1 channel x registers
(T1CHxH) inhibits output compares until the low byte (T1CHxL) is written.
Freescale Semiconductor
When the TOVx bit is at 1, setting the CHxMAX bit forces the duty cycle of buffered and unbuffered
PWM signals to 100%. As
or cleared. The output stays at the 100% duty cycle level until the cycle after CHxMAX is cleared.
When TOVx is set, a TIM1 counter overflow takes precedence over a
channel x output compare if both occur at the same time.
The 100% PWM duty cycle is defined as a continuous high level if the PWM
polarity is 1 and a continuous low level if the PWM polarity is 0. Conversely,
a 0% PWM duty cycle is defined as a continuous low level if the PWM
polarity is 1 and a continuous high level if the PWM polarity is 0.
