All rights reserved. Global timer, Private timers, and Watchdog registers 31 1 0 Reserved Event flag Figure Watchdog Interrupt Status Register bit assignment The event flag is a sticky bit that is automatically set when the Counter Register reaches zero in timer mode.

If the watchdog interrupt is enabled, Interrupt ID 30 is set as pending in the Interrupt Distributor after the event flag is set. The event flag is cleared when written with a value of 1. Trying to write a zero to the event flag or a one when it is not set has no effect.

In watchdog mode The reset flag is cleared when written with a value of 1. Trying to write a zero to the reset flag or a one when it is not set has no effect. This distinction enables software to differentiate between a normal boot sequence, reset flag is zero, and one caused by a previous watchdog time-out, reset flag set to one.

Use the Watchdog Disable Register to switch from watchdog to timer mode. The software must write 0x then 0x successively to the Watchdog Disable Register so that the watchdog mode bit in the Watchdog Control Register is set to zero. If one of the values written to the Watchdog Disable Register is incorrect or if any other write occurs in between the two word writes, the watchdog remains in its current state.

To reactivate the Watchdog, the software must write 1 to the watchdog mode bit of the Watchdog Control Register. See Watchdog Control Register on page Table B-3 Differences between issue.
