Program command
The microcomputer enters the program mode by inputting command
code “40
internal command latch at the rising edge of the WE input. When the
address which indicates a program location and data are input in the
second cycle, the M37753FFCFP and the M37753FFCHP internally
latch the address at the falling edge of the WE input and the data at
the rising edge of the WE input. The M37753FFCFP and the
M37753FFCHP start programming at the rising edge of the WE in-
put in the second cycle and finishes programming within 10 s as
measured by its internal timer. Programming is performed in units of
bytes.
Note: A programming operation is not completed by executing the

When the failure is found in this verification, the user must re-
peatedly execute the program command until the pass. Refer

Program verify command
The microcomputer enters the program verify mode by inputting
command code “C0
verify the programmed data after executing the program command.
The command code is latched into the internal command latch at the
rising edge of the WE input. When control signals are input in the
second cycle at the timing shown in Figure 10, the M37753FFCFP
and the M37753FFCHP output the programmed address’s contents
to the external. Since the address is internally latched when the pro-
gram command is executed, there is no need to input it in the sec-
ond cycle.
