APPENDIX PROM PROGRAMMING
7 WRITE command for serial programming
Operation:
FW [ _ / V ]
Option:
/V .................. Verifies data from the PROM start address after writing.
Description:
The buffer RAM data in the PROM writer is written to the S1C8F360 PROM on the target
board connected to the PROM writer. The accessed PROM address is displayed during
writing.
Option specification should be done every time the command is executed.
Example:
FW
.............
Writes data to the PROM. Data is not verified.
8 QUICK WRITE command for serial programming
Operation:
FWQ [ _ / C _ / V ]
Option:
/C .................. Writes in the clock synchronous transfer (1 Mbps) method. When omitted,
asynchronous transfer (19.2 kbps) method is used.
/V .................. Verifies data from the PROM start address after writing.
Description:
The buffer RAM data in the PROM writer is written to the S1C8F360 PROM on the target
board connected to the PROM writer. Writing by this command is faster than that of the
FW command. The accessed PROM address is displayed during writing.
Option specification should be done every time the command is executed.
Example:
FWQ
.................
Writes data to the PROM. Data is not verified.
FWQ_/C_/V
...
Writes data to the PROM in the clock synchronous transfer method, and
then verifies data.
9 READ command for serial programming
Operation:
FR [ _ / V ]
Option:
/V .................. Verifies data from the PROM start address after reading.
Description:
The contents of the S1C8F360 PROM on the target board connected to the PROM writer are
read to the buffer RAM in the PROM writer. The accessed PROM address is displayed
during reading.
Option specification should be done every time the command is executed.
Example:
FR
.............
Reads the contents of the PROM to the buffer RAM in the PROM writer. Data
is not verified.
10 VERIFY command for serial programming
Operation:
FV
Description:
Verifies the contents of the S1C8F360 PROM on the target board connected to the PROM
writer and the contents of the buffer RAM in the PROM writer. The accessed PROM
address is displayed during verification. When an error occurs, verification stops. At this
time, the address and data of the PROM and the buffer RAM data are displayed. To resume
verification, press Enter .
11 ERASE command for serial programming
Operation:
FERS [ _ / E ]
Option:
/E .................. Performs erase check from the PROM start address after erasing.
Description:
Erases the S1C8F360 PROM on the target board connected to the PROM writer.
When the PROM has been protected, the protection is cancelled after erasing.
Option specification should be done every time the command is executed.
