Note: Be aware that the IC may be damaged if parallel programming is performed by installing the IC to
the S1C6P466 Adapter Socket in the wrong direction.
(8) Erasing PROM
Clear (erase) the contents of the PROM (code PROM and data PROM) and perform erase check using
the following command.
63P466:ERSA /E
"ERASE COMPLETED" is displayed when erasing has finished normally.
In a sample chip in which the PROM has not been protected, the code PROM and data PROM can be
erased individually using the ERSI and ERSC commands, respectively. Refer to Section A.4.2, "De-
tailed description of the Universal ROM Writer II commands", for details.
Notes: Inspection data is written to the PROM at shipment, so erase it once to initialize the contents.
The PROM is protected when user data is written at Seiko Epson's factory. The protection is
released after the contents have been erased by the ERSA command.
(9) Writing user data
Write code PROM data and verify the written data using the following command.
63P466:WI /V
"WRITE COMPLETED" is displayed when writing has finished normally.
Then, write data PROM data and verify the written data using the following command.
63P466:WC /V
"WRITE COMPLETED" is displayed when writing has finished normally.
(10) Removing the S1C6P466
Remove the S1C6P466 after checking that writing has finished normally. To continue writing, repeat
from step (7) to step (10).
Note: Do not remove the S1C6P466 when the READY LED on the S1C6P466 Adapter Socket is not lit to
prevent destruction.
The name 'E0C63P466 Adapter Socket' on the
development tool is the old name of the product.
