My battery powered 16C71 application is experiencing startup problems. Every tenth or so time when I switch on power to the circuit, it just wouldn't start up. I've got a watchdog implemented and I am enabling the startup timer. Could the fact that I am enabling the startup timer have something to do with the problem? I remember reading something about the relationship between the startup timer and slow rising supply voltages and some sort of problem associated with this, but I can not for the life of me remember exactly what it was. I even tried using the PIC16C711 with brownout protection, but that also didn't seem to help. Any advice would really be appreciated.
