Figure 9 Software Watchdog, Real-Time Clock and Prescaler
The system protection control register controls system monitor functions such as the halt monitor, the
software watchdog, and the bus monitor.
REN — Real-Time Reset Enable
This bit controls whether writes to the RTP register reset the prescaler.
0 = Prescaler not reset when writing to RTP.
1 = Prescaler reset when writing to RTP.
SREN — Software Watchdog Reset Enable
This bit controls whether writes to the SWP register reset the prescaler.
0 = Prescaler not reset when writing to the SWP.
1 = Prescaler reset when writing to the SWP.
PCLK — Prescaler Clock Select
This bit selects the clock source to the prescaler.
0 = Selects system clock output divided by two (fsys ÷ 2).
1 = Selects clock synthesizer reference input divided by two (fref ÷ 2).
