output doesn't stay high

Hi,

And what about GPIO.3/MCLR ???

This is for the 12F675 using internal OSC

DEFINE OSC 4

ANSEL=%00000000
CMCON=7

LOOP:
HIGH GPIO.4
PAUSE 20
LOW GPIO.4
PAUSE 95

GOTO LOOP

for the 629 & 675:
Oscilator: INTOSC
Watchdog Timer: Enabled
Power-Up Timer: Disabled
MCLR Pin Function: Reset
Brown-Out Detect: Disabled
Code: N/P
Data EEPROM: N/P

NEVER MIND!!!!
Thanks. As I type in this message, I see that the MCLR Pin is for Reset. I changed it and reprogram and it works fine.

Thanks again for the help. I am the idiot of the day.

P.S. How come the 12f683 does not exhibit this problem? Does it have a built-in pull-up/down resistor?

All 3 of these have analog features on GPIO pins, so you'll want to disable analog for each
pin you want to use for digital output.
