Details:

In the FAQ, it mentions:

"pointers are 16 bits (function pointers are word addresses, to allow
addressing the whole 128K program memory space on the ATmega devices with > 64
KB of flash ROM)."

While true that function pointers are word addresses, the remaining text is
unclear.  Regardless of the size of the program memory space, function
pointers are limited to the first 64K words (128K bytes) of program memory
space.  The statement, as written is true, but unclear.
