I 4-bit input port (port 2): Select between pull-down resistor
input and high impedance input for each bit with the port 2 control
register (P2CON). When configured for secondary function,
an external interrupt and capture circuit trigger input are allocated.
If P2.0 to P2.3 are all set to a "H" level, the device enters system
reset mode.

I 2-bit input port (port 3): Select between pull-down resistor input and
high impedance input with the port 3 control register (P3CON).
When configured for secondary function, an external interrupt is
allocated to P3.0 and an event counter input is allocated to P3.1.

I/O 4-bit I/O port (port 6): Select between input and output, between
pull-down resistor input and high impedance input, and between
open drain output and CMOS output with the port 6 control
register (P6CON).
When configured for secondary function, an external interrupt
is allocated to these pins.
