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
