12. CONFIGURATION AREA

The device configuration area can be programmed or left

unprogrammed to select device configurations such as os-

cillator type, security bit or watchdog timer enable bit.

Four memory locations [AAAH ~ (AAA+3)H] are desig-

nated as customer ID recording locations where the user

can store check-sum or other customer identification num-

bers. These area are not accessible during normal execu-

tion but are readable and writable during program/verify

mode. It is recommended that only the 4 least significant

bits of ID recording locations are used.
