A.5.2 Universal Writer commands
This section explains the commands which can be used in RW88F360.
The following symbols have been used in the explanation:
_ indicates space
A parameter enclosed by [ ] can be omitted
, indicates selection item
indicates Enter key
1 WRITE command for parallel programming
Operation:
W [ _ / 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 PROM area in the S1C8F360 on
the socket. The accessed PROM address is displayed during writing.
Option specification should be done every time the command is executed.
Example:
W
...............
Writes data to the PROM. Data is not verified.
2 READ command for parallel programming
Operation:
R [ _ / V ]
Option:
/V .................. Verifies data from the PROM start address after reading.
Description:
The contents of the PROM in the S1C8F360 on the socket 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:
R
................. Reads the contents of the PROM to the buffer RAM in the PROM writer. Data
is not verified.
3 VERIFY command for parallel programming
Operation:
V
Description:
Verifies the contents of the PROM in the S1C8F360 on the socket and the contents of the
buffer RAM in the PROM writer. The accessed PROM address is displayed during verifica-
tion. 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 .
4 ERASE command for parallel programming
Operation:
ERS [ _ / E ]
Option:
/E .................. Performs erase check from the PROM start address after erasing.
Description:
Erases the PROM in the S1C8F360 on the socket.
When the PROM has been protected, the protection is cancelled after erasing.
Option specification should be done every time the command is executed.
5 ERASE CHECK command for parallel programming
Operation:
E
Description:
Checks that the PROM in the S1C8F360 on the socket has been erased. The PROM address
is displayed during checking. When an error occurs, erase check stops. At this time, the
address and data of the PROM are displayed. To terminate erase check, press ESC .
6 PROTECT command for parallel programming
Operation:
PROTECT
Description:
Sets the protect bit of the PROM in the S1C8F360 on the socket.
When the protect bit has been set, execution of all the commands except for ERS are
disabled.
