Notes:

1. 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.

2. The Status Register contents will repeat continuously until /CS terminates the instruction.

3. The Device ID will repeat continuously until /CS terminates the instruction.

4. The Manufacturer ID and Device ID bytes will repeat continuously until /CS terminates the instruction.

5. Unused upper address bits must be set to a 0 for the W25P10.

6. The lowest 16 address bits (A15-A0) must be set to 0.
