q Program command
The microcomputer enters the program mode by inputting com-
mand code “4016” 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 M38869FFAHP internally latches the
___
address at the falling edge of the WE input and the data at the ris-
___
ing edge of the WE input. The M38869FFAHP starts programming
___
at the rising edge of the WE input in the second cycle and finishes
programming within 10
ms as measured by its internal timer. Pro-
gramming 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 70 for the programming flowchart.
q Program verify command
The microcomputer enters the program verify mode by inputting
command code “C016” 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 68, the
M38869FFAHP outputs the programmed address’s contents to the
external. Since the address is internally latched when the program
command is executed, there is no need to input it in the second
cycle.
