Details:
This code is to intended to access the whole flash memory in devices with
flash address space bigger than 64KB.
The macro GET_FAR_ADDRESS() is the best version I've got after testing
several ones but is not always a direct replacement of the & operator for
getting far pointers. It has not been tested on ATmega2560, not even in
simulation.
The string and memory copy functions for far program memory xxxx-PF() are
still in beta stage and need more tests (not known bugs but not extensively
tested). They had been parked in my hard disk for a long time but the big ROM
devices users claim for some standard way to access the data in avr-libc.
Comments are welcomed.
Carlos Lamas.
