6.2.8.1 Watchdog Reset Reference Register (WRRR)
The watchdog reset reference register (WRRR), Figure 6-8, contains the reference value for
the software watchdog timeout causing a reset.
Table 6-9 describes WRRR fields.
6.2.8.2 Watchdog Interrupt Reference Register (WIRR)
The watchdog interrupt reference register (WIRR), Figure 6-9, contains the reference value
for the software watchdog timeout causing an interrupt.
Table 6-10 describes WIRR fields.

Reference value. Contains the reference value for the watchdog timeout causing an interrupt.
Enable interrupt. When enabled, software should periodically write to WCR to avoid reaching the
interrupt reference value.
0 Disable interrupt.
1 Enable interrupt upon reaching interrupt reference value. If IEN is set when WER[WIE] = 1, an
Reference value. This field determines the reset timeout value.Reset initializes this register to 0xFFFE,
disabling the watchdog timer and setting it to the maximum timeout value.
