Program
Setup
This command prepares the CUI for a protection register program operation. The
second cycle latches address and data, and starts the WSM’s protection register
program or lock algorithm. Toggling CE# or OE# updates the flash Status
Register data. To read array data after programming, issue a Read Array
command.
Configuration
This command prepares the CUI for device configuration. If Set Configuration
60h Configuration Register is not the next command, the CUI sets SR[5:4] to indicate command
Setup
sequence error.
Set
If the previous command was Configuration Setup (60h), the CUI latches the
03h Configuration address and writes the data from A[15:0] into the configuration register.
Register
Subsequent read operations access array data.
Note: Do not use unassigned commands. Numonyx reserves the right to redefine these codes for future functions.
