Data Sheet
The layout of the five BUSCON registers is identical. Registers BUSCON4...BUSCON1,
which control the selected address windows, are completely under software control,
while register BUSCON0, which eg. is also used for the very first code access after reset,
is partly controlled by hardware, ie. it is initialized via PORT0 during the reset sequence.
This hardware control allows to define an appropriate external bus for systems, where
no internal program memory is provided.

BUSCON1 (FF14
BUSCON2 (FF16
BUSCON3 (FF18
BUSCON4 (FF1A
Note: As default the bits BUSACT0 and ALECTL0 are set (‘1’) and bit field BTYP is
