I am trying to blink leds connected on portc in hc11 , it is in expanded mode .
here's the code :
LDAA #$FF
STAA DDRC ; Making Port C Output
LDAB #$00 ; Pulling all pins down
STAB PortC
** a delay
LDAB #$FF
STAB PortC
but nothing happens , i have measured the voltage level it never goes up or down 2.45Vdc .
any clues ?????
