Notes:
1. Data bytes are shifted with Most Significant Bit first. Byte fields with data in parenthesis “( )” 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. See Manufacturer and Device Identification table for Device ID information.
4. The Device ID will repeat continuously until /CS terminates the instruction.
5. Dual Output and Dual I/O data
IO0 = (D6, D4, D2, D0)
IO1 = (D7, D5, D3, D1)
6. Dual Input Address
IO0 = A22, A20, A18, A16, A14, A12, A10, A8 A6, A4, A2, A0, M6, M4, M2, M0
IO1 = A23, A21, A19, A17, A15, A13, A11, A9 A7, A5, A3, A1, M7, M5, M3, M1
