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