General Purpose Timer Modules
11.4
Only Timer0 has an output pin. The timer output pin is SDATAO1/TOUT0/GPO18. At reset, the function
is set to SDATAO1.
11.5
This section provides information to select the timer module’s prescaler and to configure the timer.
11.5.1
Users can select the prescalar clock from the SYSCLK (divided by 1 or by 16).
The CLK bits of the corresponding Timer Mode Register (TMR) select the clock input source. The
prescaler is programmed to divide the clock input by values from 1 to 256. The prescalar output is used as
an input to the 16-bit counter.
11.5.2
Users can configure the timer to count until it reaches a reference value at which time it either starts a new
time count immediately or continues to run. The free run/restart (FRR) bit of the TMR selects either mode.
