Value
No reset or watchdog timer timeout since the last read.
The watchdog timer timed out. These bits are cleared by a read of this
register.
This bit combination is not possible.
Reset occurred. These bits are cleared by a read of this register.
Read this register to clear periodic interrupt request. This bit always read as
zero.
Force a periodic interrupt.
