I put those changes in the code and i worked wonderfully. I've got
about a 1 sec window that needs to be refreshed throughout the code,
but it will save me from any infinite loops. Thanks for your help.

Thanks for the help ill check out the changes tomorrow morning and
report back. Again, thanks for the advice.

You have:

mov.w #WDTPW+WDTCNTCL+ WDTSSEL,& WDTCTL

This is correct -- provided that ACLK is already running at 32kHz.
Be aware that the watch crystal controlled oscilator often takes
a long time to start and there is no eazy way to check this.

Right next to that, you have:

bic.w #WDTTMSEL,&WDTCTL

This is both unnecessary and incorrect.
It is unnecessary because WDTTMSEL is already zero.
It is incorrect because you will get a WDT PW violation.

Next you have:

bis.b #WDTIE,&IE1 ; Enable WDT interrupt

This is unnecessary because WDT is in watchdog mode.

Hey,

I'm using a 1612 and i code in assembler. I'm trying to use the
watchdog in watchdog mode. I run solar cells for power, and if my
gps does not have enough power it will get locked up in my code. I'm
trying to set the watchdog for a 1000ms delay using the ACKL(32k). A
one second delay will give me enough time to run through a routine.
I'm hoping to set the watchdog throughout the main body of my code,
which takes about 3-4 secs to run, once this is completed i want the
program reset. i've attached some sample code below. thanks ahead of
time for any help.
