Watchdog Timer Operation
Enabling and Disabling the WDT
The Watchdog Timer is disabled upon a system reset (RESET). To enable the WDT, the
application program must set the WDT_EN bit (bit 7) of the WDT_CTL register. When
enabled, the WDT cannot be disabled without a RESET.
Time-Out Period Selection
There are four choices of time-out periods for the WDT—2
clock cycles. The WDT time-out period is defined by the WDT_PERIOD field of the
WDT_CTL register (WDT_CTL[1:0]). The approximate time-out periods for two
different WDT clock sources is listed in
Table 26. Watchdog Timer Approximate Time-Out Delays
RESET Or NMI Generation
Upon a WDT time-out, the RST_FLAG in the WDT_CTL register is set to 1. In addition,
the WDT can cause a RESET or send a nonmaskable interrupt (NMI) signal to the CPU.
The default operation is for the WDT to cause a RESET. It asserts/deasserts on the rising
edge of the clock. The RST_FLAG bit can be polled by the CPU to determine the source
of the RESET event.
If the NMI_OUT bit in the WDT_CTL register is set to 1, then upon time-out, the WDT
asserts an NMI for CPU processing. The RST_FLAG bit can be polled by the CPU to
