If one bit of the Address bytes (excluding the three
most significant bits which are Don’t Care) differs
from the above values, the Address will be ac-
knowledged, data will not be acknowledged and
the WRITE instruction will be ignored.
The Page Write instruction must start with the first
byte that is located in the OTP page (address 0h),
otherwise the instruction will be ignored.
The first Write to the OTP page (whether it be a 1-
byte write, a 32-byte page write, or some size in
between) will disable any further write in the OTP
page.
Let us suppose that byte N of the OTP page has
just been addressed (for example because of a
Write in the OTP page or a Random read in the
OTP page). If the next instruction uses the Current
Read Mode of the device, the first byte read in
EEPROM will be in page 0, at address N+1 (or
page 1, byte 0 if the last OTP byte addressed was
at location 31).
