REV. 1.2.3
A 16-bit down-count timer for general purpose timer or counter. Its clock source may be selected from internal
crystal oscillator or externally on pin TMRCK. The timer can be set to be a single-shot for a one-time event or
re-triggerable for a periodic event. An
interrupt may be generated in the INT Register when the timer times out. It is controlled through 4 configuration
registers [TIMERCNTL, TIMER, TIMELSB, TIMERMSB]. These registers provide start/stop and re-triggerable
or one-shot operation. The time-out output of the Timer can be set to generate an interrupt for system or event
alarm.
