Section 10 I/O Ports
10.9.4
PAPCR controls on/off of the input pull-up MOS for port A. Bits 7 to 5 are valid in modes 1 and 2
and all the bits are valid in modes 4 and 7.
10.9.5
PAODR specifies the output type of each port A pin.

Description
When in an input port state, setting the
corresponding bit to 1 turns on the input pull-up
MOS for that pin.
Description
When not specified for address output or CS7
output*, setting a PAODR bit to 1 makes the
corresponding pin an NMOS open-drain output pin,
while clearing a PAODR bit to 0 makes the
corresponding pin a CMOS output pin.
