3.5 TIMERS
The MC68302 includes three timer units: two identical general-purpose timers and a soft-
ware watchdog timer.
Each general-purpose timer consists of a timer mode register (TMR), a timer capture regis-
ter (TCR), a timer counter (TCN), a timer reference register (TRR), and a timer event register
(TER). The TMR contains the prescaler value programmed by the user. The software watch-
dog timer, which has a watchdog reference register (WRR) and a watchdog counter (WCN),
uses a fixed prescaler value. The timer block diagram is shown in Figure 3-8.
