22.10.6 TIM Channel Registers
MC68HC908GR8 — Rev 4.0
MOTOROLA
CHxMAX — Channel x Maximum Duty Cycle Bit
These read/write registers contain the captured TIM counter value of the
input capture function or the output compare value of the output
compare function. The state of the TIM channel registers after reset is
unknown.
In input capture mode (MSxB:MSxA = 0:0), reading the high byte of the
TIM channel x registers (TCHxH) inhibits input captures until the low
byte (TCHxL) is read.
In output compare mode (MSxB:MSxA 0:0), writing to the high byte of
the TIM channel x registers (TCHxH) inhibits output compares until the
low byte (TCHxL) is written.

CHxMAX
Freescale Semiconductor, Inc.
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
CHxMAX Latency
after it is set or cleared. The output stays at the 100% duty cycle level
until the cycle after CHxMAX is cleared.
