What is PUR to which you have referred here? Also, when you are talking about watchdog then whose watchdog timer you are talking about and how connectingt o XRES pin is helping.
Miniprog uses XRES pin for programming but PSoC3 does have a configurable XRES pin which can be used but I would like to know the functionality you are using here.
I need an external watchdof timer for extra security and to reset other devices includung the Psoc. I am using the MAX6301 for the timer, wired to XRES. Unfortunately XRES is also used by the programmer, hence my question, how do I overdrive the XRES so the watchdog does not interfere with the programmer?
