Name and Function
Port 5: An 8-bit input/output port. The direction of
each bit is determined by the port 5 data direction
register (P5DDR). These pins have built-in MOS
input pull-ups.
Port 6: A 4-bit input/output port. The direction of
each bit is determined by the port 6 data direction
register (P6DDR). These pins have built-in MOS
input pull-ups.
Port 7: An 8-bit input/output port. The direction of
each bit is determined by the port 7 data direction
register (P7DDR). These pins have Schmitt inputs.
Port 8: An 8-bit input port
Port 9: An 8-bit input/output port. The direction of
each bit is determined by the port 9 data direction
register (P9DDR).
