signal generated by the Force Timeout Bit.
Bit[4] Reserved. Set to 0.
Bit[5] Stop_Cnt: This is used to terminate Delay 2 (Note
Bit[6] Restart_Cnt: This is used to restart Delay 2 (Note
Bit[7] SPOFF: This is used to force a software power

1) without generating a power down. This is
used if the software determines that the power
down should be aborted. When read, this bit
indicates the following: Stop_Cnt = 0; Counter
running Stop_Cnt = 1; Counter Stopped. Note:
The write is self clearing.
1) from the button input to the generation of the
power down. When restarted, the count will
start over and delay the power down for the
time that Delay 2 is set for (Default=500msec).
The software can continue to do this
indefinately with out allowing a powerdown.
This bit is self clearing. 1=Restart;
Automatically cleared.
