Description
In mode 1, 2 (EXPE = 0), or 3:
The corresponding port A pins are output ports
when PADDR bits are set to 1, and input ports
when cleared to 0.
In mode 2 (EXPE = 1):
The corresponding port A pins are address output
when PADDR bits are set to 1, and input ports
when cleared to 0. The port A pins changes from
the address I/O ports to output ports by setting
the IOSE bit to 1.
PA7 to PA2 pins are used as the keyboard buffer
controller I/O pins by setting the KBIOE bit to 1
regardless of the operating mode, while the I/O
direction according to PA7DDR to PA2DDR is
ignored.
PADDR has the same address as PAPIN, if read,
port A status is returned.
Description
PAODR can always be read or written to,
regardless of the contents of PADDR.
