Writing the OTP Row
Writing to the OTP row (64 bytes) can only be
done once per byte, and is enabled by an instruc-
tion. This instruction is composed of three specific
WRITE operations of data bytes at three specific
memory locations followed by the data to be
stored in the OTP row (refer to

in Memory
During the WRITE operations, address bit A6 must
be zero, while address bits A5-A0 define the OTP
Row byte to be written while any EEPROM Sector
Select signal (EESi) is active. Writing the OTP
Row is allowed only when SDP mode is not en-
abled.
