The CPM includes four identical 16-bit general-purpose timers or two 32-bit timers. Each
general-purpose timer consists of a timer mode register (TMR), a timer capture register
(TCR), a timer counter (TCN), a timer reference register (TRR), a timer event register
(TER), and a timer global conÞguration register (TGCR). The TMRs contain the prescaler
values programmed by the user.
Figure 17-1 shows the timer block diagram.
