Following the Intelligent Identifier command, two read operations access the manufacturer and device signature codes.
The CSR is automatically available after device enters data program, block erase, or suspend operations.
Clears CSR.3, CSR.4 and CSR.4. Also clears GSR.4 and all BSR.4 and BSR.2 bits.
The upper byte of the data bus (DQ
8
–15
) during command writes is a
“Don’t Care” in x16 operation of the device.
