PEPROM Programming
access one byte of eight PEPROM locations. Reset clears the
PEPROM bit select register, thereby setting the PEPRZF bit by
default.
1 = Row zero selected
0 = Row zero not selected

12.4 PEPROM Programming
Factory-provided software for programming the PEPROM is available on
the World Wide Web at:
http://www.motorola.com/mcu/
NOTE:
While the PEPGM bit is set and the V_PP voltage level is applied to the
IRQ/V_PP pin, do not access bits that are to be left unprogrammed
(erased).
To program the PEPROM bits properly, the V_DD voltage must be greater
than 4.5 Vdc.
