Program and Verify EPROM
In the Program and Verify EPROM routine, the contents of the external EPROM are copied into
the EPROM areas of the MC68HC705F8 device. There is a direct correspondence of addresses
between the two devices. Non-EPROM addresses are ignored so data contained in those areas
are not accessed. Unprogrammed EPROM address locations should contain $FF to speed up the
programming operation. During the programming routine the Program/Verify LED is illuminated.
At the end of the programming routine, the LED is turned off, and the verication routine is entered.
If the contents of the EPROM and external EPROM exactly match, then the Veried LED is
illuminated. The verication routine stops if a discrepancy has been detected.
