Notes:

1. (BR7-BR0) : The output data of block protection register.

2. The Block Protection Registers contents will repeat continuously until CS# terminates the instruction.

3. Data bytes are shifted with Most Significant Bit first. Byte fields with data in parenthesis â( )â indicate data being read from the

device on the DO pin.

4. The Status Register contents will repeat continuously until CS# terminate the instruction.

5. The Device ID will repeat continuously until CS# terminates the instruction.

6. The Manufacturer ID and Device ID bytes will repeat continuously until CS# terminates the instruction.

00h on Byte 4 starts with MID and alternate with DID, 01h on Byte 4 starts with DID and alternate with MID.

7. (M7-M0) : Manufacturer, (ID15-ID8) : Memory Type, (ID7-ID0) : Memory Capacity.
