9.4.4 Secure PROM and Verify
9.4.5 Secure PROM and Dump
MC68HC705C8A — Rev. 3
MOTOROLA
This routine is used after the PROM is programmed successfully to
verify the contents of the MCU PROM against the contents of the
EPROM and then to secure the PROM. To accomplish this routine, take
these steps:
No LED is illuminated during this routine. Further, the end of the routine
does not mean that the SEC bit was verified. To ensure that security is
properly enabled, attempt to perform another verify routine. If the green
LED does not light, the PROM has been secured properly.
This routine is used after the PROM is successfully programmed to
dump the contents of the MCU PROM through the SCI (binary upload)
and then to secure the PROM. To accomplish this routine, take these
steps:
1. Set switch 1 in the ON position (restores V
2. Restore V
3. Set switches S4 and S6 in the OFF position.
4. Set switches S3 and S5 in the ON position.
5. Set switch 2 in the OUT position (routine is activated).
6. Set switch 2 in the RESET position when the routine is completed.
1. Set switch 1 in the ON position (restores V
2. Restore V
3. Set switch S6 in the OFF position.
4. Set switches S3, S4, and S5 in the ON position.
5. Set switch 2 in the OUT position (routine is activated).
6. Set switch 2 in the RESET position when the routine is completed.
