in the first cycle. The command code is latched
into the internal command latch at the rising edge of the WE input.
When the address which indicates a program location and data is
input in the second cycle, the 3803/3804 group internally latches
the address at the falling edge of the WE input and the data at the
rising edge of the WE input. The 3803/3804 group starts program-
ming at the rising edge of the WE input in the second cycle and
finishes programming within 10
μ
s as measured by its internal
timer. Programming is performed in units of bytes.
Note:
A programming operation is not completed by executing the
program command once. Always be sure to execute a pro-
gram verify command after executing the program command.
When the failure is found in this verification, the user must re-
peatedly execute the program command until the pass. Refer
to Figure 92 for the programming flowchart.

Program verify command
The microcomputer enters the program verify mode by inputting
command code

in the first cycle. This command is used to
verify the programmed data after executing the program com-
mand. 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 90, the
3803/3804 group outputs 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
second cycle.
