Hello, i have a "simple" problem, im setting and clearing an output pin (PTB0) in my program but it doesn´t change, i have changed the output to PTB6 but it neither works (output initialization included), I have other 2 output pins int PTBA and they work well, i dont find the reason of failure... Can anyone help please?
This is my code:
;*** port Init
LDA #$0C ; PTA0 and PTA1 as input
CLR PTAD ; PTA2 and PTA3 outputs (this 2 are working)
STA PTADD ;
LDA #$03 ; PTB0 and PTB1 outputs
CLR PTBD ; the rest inputs
STA PTBDD ;
;***port def ***
SalFRE EQU 6 ;Out in (PTB0)
;*** main ***
FRE_DI BCLR SalFRE,PTBD ; 2 ms pulse
JSR DLY2
BSET SalFRE,PTBD
RTS
;**** Then added a bigger pulse duration to appreciate the change in a LED
FRE_DI BCLR SalFRE,PTBD ; 402 ms total pulse duration
JSR DLY100
JSR DLY100
JSR DLY100
JSR DLY100
JSR DLY2
BSET SalFRE,PTBD
RTS
