Function
This is an 4-bit I/O port equivalent to P6. Additional software-selectable
secondary functions are: 1) P90 to P92 can act as Timer B0~B2 input
pins.
This is an 8-bit I/O port equivalent to P6. This port can also function as
A/D converter input pins, as selected by software. Furthermore, P104 to
P107 can also function as input pins for the key input interrupt function.
