NOTES:
-IOWR, -IORD,
1. The Setup time is determined by the value programmed into the Setup Timing register, index 3Ah/3Dh. Using the Timer Set
2. The Command time is determined by the value programmed into the Command Timing register, index 3Bh/3Eh. Using the
3. The Recovery time is determined by the value programmed into the Recovery Timing register, index 3Ch/3Fh. Using the
4. -IOIS16 level from card must be valid within 3 clocks of an address change to the card.
