Output $FF on SCI transmitter.
Erase EEPROM array.
Verify that EEPROM has been erased. If it has not, repeat erase procedure.
Write $FF to every location in RAM.
Check EPROM for data. If data is present, stay in loop. Otherwise proceed.
Erase the CONFIG register.
Continue executing bootloader routine.
Notice that the bootloader routine checks the EPROM to see if it contains any data. The presence of
data causes the routine to stay in a loop. At this time, devices with the security enhancement are only
available as one-time-programmable (OTP) MCUs in non-windowed packages. Once they have been
programmed and secured, they will not function in bootstrap mode.
For more information refer to M68HC11 Reference Manual (M68HC11RM/AD).
