0 Action on next watchdog timer time-out is to set TSR[ENW]
1 Action on next watchdog timer time-out is governed by TSR[WIS]
When a watchdog timer time-out occurs while WIS = 0 and the next watchdog time-out is enabled
(ENW = 1), a watchdog timer exception is generated and logged by setting WIS. This is referred to as
a watchdog timer first time out. A watchdog timer interrupt occurs if enabled by TCR[WIE] and
MSR[CE]. To avoid another watchdog timer interrupt once MSR[CE] is reenabled, (assuming
TCR[WIE] is not cleared instead), the interrupt handler must reset TSR[WIS].
Watchdog timer interrupt status. Functions as write-one-to-clear.
0 A watchdog timer event has not occurred.
1 A watchdog timer event occurred. When MSR[CE] = 1 and TCR[WIE] = 1, a watchdog timer

1 A decrementer event occurred. When MSR[EE] = TCR[DIE] = 1, a decrementer interrupt is taken.
