Programmable Interrupt Timer Modules (PIT1 and PIT2)
The read/write PRE[3:0] bits select the system clock divisor to
generate the PIT clock as
To accurately predict the timing of the next count, change the
PRE[3:0] bits only when the enable bit (EN) is clear. Changing the
PRE[3:0] resets the prescaler counter. System reset and the loading
of a new value into the counter also reset the prescaler counter.
Setting the EN bit and writing to PRE[3:0] can be done in this same
write cycle. Clearing the EN bit stops the prescaler counter.
The read/write PDOZE bit controls the function of the PIT in doze
mode. Reset clears PDOZE.
When doze mode is exited, timer operation continues from the state
it was in before entering doze mode.
