change.
Some parametric limits are subject to
Software Commands
Table 26 lists the software commands.
After setting the CPU Rewrite Mode Select Bit to
“
1
”
, write a soft-
ware command to specify an erase or program operation.
Each software command is explained below.
G
Read Array Command (FF
16
)
The read array mode is entered by writing the command code
“
FF
16
”
in the first bus cycle. When an address to be read is input in
one of the bus cycles that follow, the contents of the specified ad-
dress are read out at the data bus (DB
0
to DB
7
).
The read array mode is retained intact until another command is
written.
G
Read Status Register Command (70
16
)
When the command code
“
70
16
”
is written in the first bus cycle,
the contents of the status register are read out at the data bus
(DB
0
to DB
7
) by a read in the second bus cycle.
The status register is explained in the next section.
G
Clear Status Register Command (50
16
)
This command is used to clear the bits SR4 and SR5 of the status
register after they have been set. These bits indicate that opera-
tion has ended in an error. To use this command, write the
command code
“
50
16
”
in the first bus cycle.
G
Program Command (40
16
)
Program operation starts when the command code
“
40
16
”
is writ-
ten in the first bus cycle. Then, if the address and data to program
are written in the 2nd bus cycle, program operation (data program-
ming and verification) will start.
Whether the write operation is completed can be confirmed by
reading the status register or the RY/BY Status Flag. When the
program starts, the read status register mode is entered automati-
cally and the contents of the status register is read at the data bus
(DB
0
to DB
7
). The status register bit 7 (SR7) is set to
“
0
”
at the
Table 26 List of software commands (CPU rewrite mode)
same time the write operation starts and is returned to
“
1
”
upon
completion of the write operation. In this case, the read status reg-
ister mode remains active until the next command is written.
The RY/BY Status Flag is
“
0
”
during write operation and
“
1
”
when
the write operation is completed as is the status register bit 7.
At program end, program results can be checked by reading the
status register.
