FP-80A I/O Name and Function
each bit is determined by the port 5 data direction
register (P5DDR). These pins have built-in MOS
input pull-ups.
each bit is determined by the port 6 data direction
register (P6DDR). These pins have built-in MOS
input pull-ups.
each bit is determined by the port 7 data direction
register (P7DDR). These pins have Schmitt inputs.
Port 8: An 8-bit input port
each bit is determined by the port 9 data direction
register (P9DDR).
