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 that the address is changing earlier as 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.
