In single chip mode, these are general purpose I/O pins. When set for
input, they can be set by the pull-up resistance setting register (RDR0).
When set for output, this setting will be invalid.
In external bus mode, these pins function as address low output/data low
I/O pins.
In single chip mode, these are general purpose I/O pins. When set for
input, they can be set by the pull-up resistance setting register (RDR1).
When set for output, the setting will be invalid.
In external bus mode, these pins function as address middle output/data
high I/O pins.
In single chip mode this is a general-purpose I/O port.
