I am writing a little routine that will input characters and print them to the screen (There is more involved than that, but this will do for now) Anyway, I want to use a CIA TOD clock to check and see if no keys have been pressed for xx amount of time. Here is a code snippet. I have it set to see if it will idle out at 1 minute TIMER = $DD08 ; CIA2 LDA #0 ; set TOD to all 0's STA TIMER+3 STA TIMER+2 STA TIMER+1 STA TIMER+0 BACK JSR $FFE4 STA TEMP LDA TIMER+2 ; READ IN THE MINUTES CMP #$01 ; SEE IF IT = # OF MINUTES IN BCD FORMAT BEQ + LDA TEMP BEQ BACK JSR $FFD2 LDA #0 STA TIMER+2 ; Set minutes to 0 again ?? JMP BACK ; OK IT IDLED OUT, EXIT + INC $D020 RTS temp .by 0 Ok, when I run this program the first time, it seems to work ok. When location $DC0A (CIA 1 minutes) = #$01 it will go to the idle routine which simply changes the border color and exits. The problem is that if I enter this routine again, it never sets the TOD clock back to 0 and thus exits right away (providing that location $DC0A didnt update to #$02) If anyone can tell me what I am doing wrong I would appreciate it.
