Input command code 2516 in the first transfer. Proceed and input the
low-order 8 bits and high-order 8 bits of the address and the low-
order 8 bits and high-order 8 bits of program data, and pull the PGM

the program command is read and verified and stored into the in-
ternal data latch. When the PGM pin is released back to “H”, the
verify data that has been stored into the data latch is serially output
from the SDA pin.
Note. When outputting the verify data, the SDA pin is switched for output at the first falling of the serial clock. The SDA pin is placed in
the high-impedance state during the th(C–E) period after the last rising edge of the serial clock (at the 16th bit).
pin to “L”. When this is done, the program data is programmed to
the specified address.
