7.5 TIMERS
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), and a timer event register
(TER). The TMR contains the prescaler value programmed by the user. In addition, there is
one timer global configuration register (TGCR). The timer block diagram is shown in Figure
7-6.
7.5.1 Timer Key Features
The four identical general-purpose timers have the following features:
• Maximum Period of 10.7 Sec (at 25 MHz)
• 40-ns Resolution (at 25 MHz)
• Programmable Sources for the Clock Input
lization level.

The general-purpose timers are up-counters, but the RISC tim-
ers are down-counters. The user should consider this fact when
comparing timer counts.
