1-7-2. Writing and Rewriting PLD Internal
Data
The device is equipped with a PLD (Programmable Logic
Device) that can be written and rewritten using the e-
Production (EPR) method.
When replacing the following parts or upgrading the PLD
version, contact your local Sony Sales Office/Service
Center.
n
The part number of the PLD (or the ROM for the PLD)
noted in “Spare Parts” is for a part with no data written.
When you need to replace any part, write data using the
steps on the next page.
For a PLD that has a program operating on the externally
connected ROM, when a part in the PLD is defective, if
you replace only the defective part, you do not have to
rewrite the data.
