(3) How to use the data security function
"Data security" is the disabled function to read the data of the EPROM.
The following is the process in order to execute data security.
1. Set 'ON' the jumper of attachment.
2. Program again. Then the EPROM programmer displays the error. The error means normally activity of the
data security. It is not a trouble of the EPROM programmer or the LSI.
Notes
Data security is not executed when the data of all address have 'FFH' at the sequence 2 above.
The programming by sequential operation "BLANK
→
PROGRAM
→
VERIFY" cannot be executed data
security at the sequence 2 above.
Set 'OFF' to the jumper after executing the data security.
(4) How to eliminate
The programming data can be erased by using the EPROM eraser.
(5) Shielding
The UVEPROM (ultraviolet erasable and programmable ROM) is in it. Put the seal on the window in use.
