NOTES:

1. ACK can shorten the CS pulse width.

Wait States (WS) can be programmed in the Chip Select X Register, Bit field WaitP and WaitX. It can be specified from

0–65535.

2. In Large Flash and MOST Graphics mode the shared PCI/ATA pins, used as address lines, are released at the same moment

as the CS. This can cause the address to change before CS is deasserted.

3. ACK is input and can be used to shorten the CS pulse width.

4. Only available in Large Flash and MOST Graphics mode.

5. Only available in MOST Graphics mode.

6. Deadcycles are only used, if no arbitration to an other module (ATA or PCI) of the shared local bus happens. If arbitration

happens the bus can be driven within 4 IPB clocks by an other modules.
