Disabling MCLR pin
I am trying to disable the MCLR pin because I am using it to do a LCDOUT on that Pin.
I am using a PIC16F88.
I read this thread but it is not helping me out.
I still get compiling error.. illegal upcode
Code:
'LCD testing program and Clock viewing
INCLUDE "modedefs.bas"
OSCCON = %01110000 '8 Mhz
Define OSC 8
CMCON = 7 : ANSEL = 0 : ADCON1 = 7
@ DEVICE pic16F88, MCLR_OFF
'/////////////////////////
'// LCD configuration //

Re: Disabling MCLR pin
DATA sheets are your friend.
Please read the chips DATA sheet and make it happy :)
MCLR is an input only.
