[WRITE PROCEDURE 1]
1.
Apply a “L” level to the
CS pin to enable parallel interface.
2.
Apply a “H” level to the ALE pin.
3.
Set address values to the AD0 to AD7 pins.
4.
Apply a “L” level to the ALE pin. (Set up the addresses at the fall of ALE.)
5.
Apply a “L” level to the
WR pin.
6.
Input date to the AD0 to AD7 pins.
7.
Apply a “H” level to the
WR pin to write data. (Data writing ends at the rise of WR.)
8.
Apply a “H” level to the
CS pin to terminate the use of parallel interface.
