System Integration Module (SIM)
If an interrupt timeout value is programmed in WIRR, and this value is reached prior to the reset timeout
value, WER[WIE] is set and a maskable interrupt is issued at the level defined by ICR4[SWTOIPL].
The software watchdog consists of a 15-bit counter with a 15-bit prescaler. It counts up to a maximum of
32768, with a resolution of 32768 clock periods. Thus, at 66 MHz, the resolution of the watchdog is 0.5
msec, with a maximum timeout period of 32768 * 32768 = 2

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.
Enable watchdog. When enabled, software should periodically write to WCR to avoid reaching the reset
reference value.
