DEVICE CONFIGURATION AREA
The Device Configuration Area can be programmed or left
unprogrammed to select device configuration such as secu-
rity bit.
Ten memory locations (0F50
H
~ 0FE0
H
) are designated as
Customer ID recording locations where the user can store
check-sum or other customer identification numbers.
This area is not accessible during normal execution but is
readable and writable during program / verify.
