| |Procedure: Set mask register to $7ff. Read data |

| |Compare data register with original value, repeat |
| |until data register returns to original value to |
| |ensure data has been sent over the interface. |
| +-----------------------------------------------------+
| |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. |
