Timer Interface Module (TIM)

Technical Data

MC68HC908GR8 — Rev 4.0

358

Timer Interface Module (TIM)

MOTOROLA

NOTE:

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.

TOVx — Toggle On Overflow Bit

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.

1 = Channel x pin toggles on TIM counter overflow.

0 = Channel x pin does not toggle on TIM counter overflow.

NOTE:

When TOVx is set, a TIM counter overflow takes precedence over a

channel x output compare if both occur at the same time.
