9.4 PROM Programming Routines
9.4.1 Program and Verify PROM
MC68HC705C8A — Rev. 3
MOTOROLA
This subsection describes the routines necessary to program, verify, and
secure the PROM device, and other routines available to the user.
The program and verify PROM routine copies the contents of the
external EPROM into the MCU PROM with direct correspondence
between the addresses. Memory addresses in the MCU that are not
implemented in PROM are skipped. Unprogrammed addresses in the
EPROM being copied should contain $00 bytes to speed up the
programming process.
To run the program and verify the PROM routine on the PROM MCU,
take these steps:
At this point, if no other MCU is to be programmed or secured, remove
V
MCU being programmed, the user can then set switches S3, S4, S5, and
S6 to the positions necessary to select the next routine, and begin the
routine by setting switch 2 to the OUT position. If no other routine is to
be performed, remove V
the programming socket.

The red light-emitting diode (LED) is illuminated, showing that the
programming part of the routine is running. The LED goes out
when programming is finished. The verification part of the routine
now begins. When the green LED is illuminated, verification is
successfully completed and the routine is finished.
