18.2 CPM General-Purpose Timers
The CPM has four identical 16-bit general-purpose timers that can be cascaded into two
32-bit timers. Note that the CPM general-purpose timers are separate and distinct from the
RISC timer tables described in Section 19.7, ÒThe RISC Timer Table.Ó Each timer consists
of the following:
¥ Timer mode register (TMR)
¥ Timer capture register (TCR)
¥ Timer counter (TCN)
¥ Timer reference register (TRR)
¥ Timer event register (TER)
¥ Timer global conÞguration register (TGCR).
