Help! Needed? in Mikroc, why is this not working?

Hwlp In mikroc why is this not working PORTC.F0 = ~PORTC.F0 or PORTC.F0 = !PORTC.F0 with tris set up.

Hwlp In mikroc why is this not working PORTC.F0 = ~PORTC.F0 or PORTC.F0 = !PORTC.F0 with tris set up.

All above are working for me but with PORTB:
 PORTB.F0 = ~PORTB.F0;
 PORTB.F0 = !PORTB.F0;

Has your PIC PORT C? (in my case the PIC16F628A has only A and B ports)

Hi Jaikumar,
Please read carefully the data sheet:
http://ww1.microchip.com/downloads/en/devicedoc/41202C.pdf

An extract from this:

4.3 PORTC

Note: The ANSEL (91h) and CMCON0 (19h)
registers must be initialized to configure
an analog channel as a digital input. Pins
configured as analog inputs will read ‘0’.

EXAMPLE 4-3: INITIALIZING PORTC

BCF STATUS,RP0 ;Bank 0
CLRF PORTC ;Init PORTC
MOVLW 07h ;Set RC<4,1:0> to
MOVWF CMCON0 ;digital I/O
BSF STATUS,RP0 ;Bank 1
CLRF ANSEL ;digital I/O
MOVLW 0Ch ;Set RC<3:2> as inputs
MOVWF TRISC ;and set RC<5:4,1:0> as outputs
BCF STATUS,RP0 ;Bank 0

Hope this helps!
