Step 4
Clear the block protect register (BPROT) to allow programming of the
MC68HC811E2 EEPROM.
At the PCbug11 command prompt, type
MS 1035 00
Step 5
PCbug11 defaults to a 512-byte EEPROM array located at $B600. This
must be changed since the EEPROM is, by default, located at $F800 on
the MC68HC811E2.
At the PCbug11 command prompt, type
EEPROM 0
Then type: EEPROM F800 FFFF
EEPROM 103F 103F
This assumes you have not relocated the EEPROM by previously
reprogramming the upper 4 bits of the CONFIG register. But if you have
done this and your S records reside in an address range other than
$F800 to $FFFF, you will need to first relocate the EEPROM.
Step 6
Erase the CONFIG to allow programming of NOSEC bit (bit 3). It is also
recommended to program the EEPROM at this point before
programming the CONFIG register. Refer to the engineering bulletin
Programming MC68HC811E2 Devices with PCbug11 and the
M68HC711E9PGMR
, Motorola document number EB184.
At the PCbug11command prompt, type
EEPROM ERASE BULK 103F
