Memory Maps and Registers
Memory Maps and Registers
When programming the tick timer for periodic interrupt, the counter should be cleared to
zero by software and then enabled. If the counter does not initially start at zero, the time to
the first interrupt may be longer or shorter than expected. Note that the rollover time for the
counter is 71.6 minutes.
Since the processor is 16-bits and the tick timer is 32-bits, the compare register was split
in half. Accessing the whole register will require two transactions.
