NOTE:
References to either timer 1 or timer 2 may be made in the following text
by omitting the timer number. For example, TCH0 may refer generically
to T1CH0 and T2CH0, and TCH1 will refer to T1CH1.
The Timer Interface Module in MC68HC908GR8 is constructed by TIM1
which is contained channel 0 and 1, and TIM2 which is contained
channel 0 only.
References to TCLK and external TIM clock input are only valid if the
MCU has an external TCLK pin. If the MCU has no external TCLK pin,
the TIM module must use the internal bus clock prescaler selections.
Figure 22-1
the TIM is the 16-bit TIM counter that can operate as a free-running
counter or a modulo up-counter. The TIM counter provides the timing
reference for the input capture and output compare functions. The TIM
counter modulo registers, TMODH:TMODL, control the modulo value of
the TIM counter. Software can read the TIM counter value at any time
without affecting the counting sequence.
The TIM channels (per timer) are programmable independently as input
capture or output compare channels. If a channel is configured as input
capture, then an internal pullup device may be enabled for that channel.
