Many thanks to the following people for their contributions!
Markus Gutschke, Alexander Herzlinger, Karsten Isakovic, Thomas Binder,
Julian Reschke, Georges Kesseler, Torbjoern Ose
New in this revision : MAJOR CHANGES! Totally re-organized. Completely
reformatted to 80 columns! Moved things around into a more logical order.
Added "official" OS variables. Added IDE error register (Falcon030/STbook)
thanks to XHDI 1.10 documentation. Now will someone send the rest of the IDE
documentation?
Last few revisions: Cookie jar documentation cleaned up - should be readable
now! A few minor additions (SCC interrupt vectors) and corrections. ACIA
Additions. Extended joystick ports. Master 32bit memory map. Full YM2149
register listing. Various typo corrections.
Still need info on: Floating Point Coprocessor ($FFFA40-$FFFA58)
Realtime Clock ($FFFC21-$FFFC3F)
IDE Controller ($F00000-$F00039)
STACY Display Driver ($FF827E)
Mega STe Cache/Processor Control - Might find myself ($FF8E21)
TT-SCSI Drive Controller NCR-5380 ($FF8781-$FF878F)
TT Clock Chip MC146818A ($FF8961-$FF8963)
Falcon030 NVRAM Addresses - Might find these myself ($??????-$??????)
Any Falcon030 registers I missed - especially video ($??????-$??????)

| |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. |
