Command
This command prepares the CUI for a protection register program operation. The
second cycle latches address and data, and starts the WSM protection register
program or lock algorithm. Toggling CE# or OE# updates the flash device status
register data. To read array data after programming, issue a Read Array
command.
This command prepares the CUI for flash device configuration. If Set
Configuration Register is not the next command, the CUI sets SR[5:4] to indicate
a command sequence error.
If the previous command was Configuration Setup (60h), the CUI latches the
address and writes the data from A[15:0] into the configuration register.
Subsequent read operations access the array data.
