52 / 102 page Numonyx™ Wireless Flash Memory (W18) Datasheet November 2007 52 Order Number: 290701-18 Numonyx™ Wireless Flash Memory (W18) Protection C0h Protection 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 60h Configuration Setup This command prepares the CUI for device configuration. If Set Configuration Register is not the next command, the CUI sets SR[5:4] to indicate command sequence error. 03h Set Configuration Register 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 array data. Note: Do not use unassigned commands. Numonyx reserves the right to redefine these codes for future functions.
