Table with hardware IO handlers for the TT.
|
|
|
|
NOTE [NP] : contrary to some unofficial documentations, the TT doesn't have
|
|
hardware scrolling similar to the STE. As such, registers FF820E,
|
|
FF820F, FF8264 and FF8265 are not available and seem to return undefined values
|
|
based on the data last seen on the bus (this would need more tests on a TT)
|
|
move.b $ff820e,d0 -> FF
|
|
move.b $ff820f,d0 -> 01
|
|
move.b $ff8264,d0 -> 82
|
|
move.b $ff8265,d0 -> 65
