Software Commands
Table 23 lists the software commands.
After setting the CPU reprogram mode select bit to “1”, write a soft-
ware command to specify an erase or program operation.
The content of each software command is explained below.
Read Array Command (FF16)
The read array mode is entered by writing the command code “FF16
in the first bus cycle. When an address to be read is input in next bus
cycles, the content of the specified address is read out at the data
bus (D0–D7).
The read array mode is retained intact until another command is writ-
ten. And after power on and after recover from deep power down
mode, this mode is selected also.
Table 23 List of software commands (CPU rewrite mode)
Read Status Register Command (7016)
When the command code “7016” is written in the first bus cycle, the
content of the status register is read out at the data bus (D0–D7) by a
read in the second bus cycle.
The status register is explained in the next section.
Clear Status Register Command (5016)
This command is used to clear the bits SR1,SR4 and SR5 of the
status register after they have been set. These bits indicate that op-
eration has ended in an error. To use this command, write the com-
mand code “5016” in the first bus cycle.
