Datasheet
NOTES:
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. For typical active timing programmed at 340 ns, maximum -WAIT timing is 200 ns after Command active.
5. -IOIS16 must go low within 3Tcp + 20 ns of the cycle beginning or -IOIS16 will be ignored and -CE will not be activated.
