It's much the same as INHX8M format except address specifiers are placed
in the file like this one at the start which set the upper 16 bits of
the program counter address. This value stays there until changed which
would happen if the fuses or config bits are included in the listing.
The address specifier is supplied when '04' is the record type as shown
below.

:020000040000FA

Program counter would be 0000 xxxxh

At ID Locs

:020000040020DA

Program counter would be 2000 xxxxh


At fuses

:020000040030CA

Program counter would be 3000 xxxxh


Fuse data on next line

:08000000FFFFFBFDFFFFFFFF06

Address is specified as 0000 so PC address = 3000 0000
