Description
SRESET# 1 = Pin 26 is the input pin as PD# signal. 0 = Pin 26 is the output pin as SRESET# signal.
Frequency This bit allows setting the Revert Frequency once the system is rebooted due to Watchdog time
Revert
out only.0 = selects frequency of existing H/W setting1 = selects frequency of the second to last
S/W setting (the software setting prior to the one that caused a system reboot).
WDTEST WD-Test, ALWAYS program to “0.”
WD Alarm This bit is set to “1” when the Watchdog times out. It is reset to “0” when the system clears the
WD time stamps (WD3:0).
