Note:
Write to Lock Register (WRLR)
The Write to Lock Register (WRLR) instruction is decoded only in the M25PE40 in the T9HX
process (see
The Write to Lock Register (WRLR) instruction allows bits to be changed in the Lock
Registers. Before it can be accepted, a Write Enable (WREN) instruction must previously
have been executed. After the Write Enable (WREN) instruction has been decoded, the
device sets the Write Enable Latch (WEL).
The Write to Lock Register (WRLR) instruction is entered by driving Chip Select (S) Low,
followed by the instruction code, three address bytes (pointing to any address in the targeted
sector and one data byte on Serial Data input (D). The instruction sequence is shown in
Figure
latched in, otherwise the Write to Lock Register (WRLR) instruction is not executed.
Lock Register bits are volatile, and therefore do not require time to be written. When the
Write to Lock Register (WRLR) instruction has been successfully executed, the Write
Enable Latch (WEL) bit is reset after a delay time less than t
Any Write to Lock Register (WRLR) instruction, while an Erase, Program or Write cycle is in
progress, is rejected without having any effects on the cycle that is in progress.
