UNIVERSAL (3.3V AND 5V) PCI BUS DUAL UART
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 continuous interval. 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.

IMER
Logic zero (default) disables Timer-Counter interrupt and logic one enables the interrupt, reading the
TIMERCNTL clears the interrupt.
Logic zero (default) stops/pauses the timer and logic one starts/re-starts the timer/counter.
Logic zero (default) selects re-trigger timer function and logic one selects one-shot (timer function.
Logic zero (default) selects internal and logic one selects external clock to the timer/counter.
Routes the Timer-Counter interrupt to MPIO[0] if MPIOSEL[0]=0 for external event control.
Reserved (defaults to zero).
