WREN/WRDS
The CAT24C44 powers up in the program disable state
(the “write enable latch” is reset). Any programming
after power-up or after a WRDS (RAM write/E2PROM
store disable) instruction must first be preceded by the
WREN (RAM write/E2PROM store enable) instruction.
Once writing/storing is enabled, it will remain enabled
until power to the device is removed, the WRDS instruc-
tion is sent, or an E2PROM store has been executed

(STO). The WRDS (write/store disable) can be used to
disable all CAT24C44 programming functions, and will
prevent any accidental writing to the RAM, or storing to
the E2PROM.
Data can be read normally from the CAT24C44 regard-
less of the “write enable latch” status.
