Reads data stored in memory, start-
ing at specified address (.Note).
Erase/Write Enable must precede all
programming modes.
Erase data at specified address
location if address is unprotected
(Note).
Erase all registers to “FF”. Valid only
when Protect Register is cleared.
Writes register if address is unpro-
tected.
Writes all registers. Valid only when
Protect Register is cleared.
Erase/Write Disable deactivates all
programming instructions.
Reads address stored in Protect
Register.
Must immediately precede
PRCLEAR, PRWRITE and PRDS
instructions.
Clears the Protect Register such that
all data are NOT write-protected.
Programs address into Protect Reg-
ister. Thereafter, memory addresses
greater than or equal to the address
in Protect Register are write-pro-
tected.
ONE TIME ONLY instruction after
which the address in the Protect
Register cannot be altered.
