General-Purpose Timers
■ Timer1: 0x4003.1000
■ Timer2: 0x4003.2000
Note that the Timer module clock must be enabled before the registers can be programmed (see
page 210). There must be a delay of 3 system clocks after the Timer module clock is enabled before
any Timer module registers are accessed.
