- | |Interrupts: Timer A can be set to interrupt at the |
- | |end of a frame. Alternatively, the GPI7 (MFP mono |
- | |detect) can be used to generate interrupts thereby |
- | |freeing up Timer A. In this case, the active edge |
- | |$FFFA03 must be set by or-ing the active edge of |
- | |$FFFA03 with the contents of $FF8260: |
- | |$FF8260 - 2 (mono) or.b #$80 with edge |
- | |$FF8260 - 0,1 (colour) and.b #$7F with edge |
- | |This will generate an interrupt at the START of a |
- | |frame, instead of at the end as with Timer A. To |
- | |generate an interrupt at the END of a frame, simply |
- | |reverse the edge values. |
