Application Note
20
The conversion of the linear S-record load address to a PPAGE number
and a PPAGE window address can be performed by the two formulas
shown in
the PPAGE register, PPAGEWinSize is the size of the PPAGE window
which is $4000. In the second formula, PPAGEWinAddr is the address
within the PPAGE window where the S-record code/data is to be loaded.
PPAGEWinStart is the beginning address of the PPAGE window which
is $8000.
