1. Command cycle is two clock periods in SQI mode and eight clock periods in SPI mode.

2. Address bits above the most significant bit of each density can be VIL or VIH.

3. Address, Dummy/Mode bits, and Data cycles are two clock periods in SQI and eight clock periods in SPI mode.

4. RST command only executed if RSTEN command is executed first. Any intervening command will disable Reset.

5. Device accepts eight-clock command in SPI mode, or two-clock command in SQI mode.

6. Data cycles are two clock periods. IOC bit must be set to ‘1’ before issuing the command.

7. Address, Dummy/Mode bits, and data cycles are two clock periods. IOC bit must be set to ‘1’ before issuing the command.

8. Data cycles are four clock periods.

9. Address, Dummy/Mode bits, and Data cycles are four clock periods.

10. Sector Addresses: Use AMS - A12, remaining address are don’t care, but must be set to VIL or VIH.

11. Blocks are 64 KByte, 32 KByte, or 8KByte, depending on location. Block Erase Address: AMS - A16 for 64 KByte; AMS - A15

for 32 KByte; AMS - A13 for 8 KByte. Remaining addresses are don’t care, but must be set to VIL or VIH.
