11.10.5 TIM Channel Registers
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
NOTE:
NOTE:
Before enabling a TIM channel register for input capture operation, make
sure that the TCHx pin is stable for at least two bus clocks. User software
should also clear CHxF before setting CHxIE to avoid any false
interrupts.
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.
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.
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 1, setting the CHxMAX bit forces the
duty cycle of buffered and unbuffered PWM signals to 100%. As
Figure 11-11
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
