Description
4-bit input port (P0):
Selectable as pull-up resistor input, pull-down resistor
input, or high impedance input by the port 01 control
register (P01CON).
As secondary functions, P0.0 to P0.3 are assigned
external interrupt functions, P0.0 and P0.1 are assigned
a capture trigger function, and P0.3 is assigned an
analog comparator input for battery check.

4-bit input-output port (P2):
Following can be specified for each bit by the port 2
control registers 0 to 3 (P20CON to P23CON): (1) input
or output, (2) pull-up/pull-down resistor input or high
impedance input, and (3) NMOS open drain output or
CMOS output.
As secondary functions, P2.0 to P2.3 are assigned
external interrupt functions.

or output, (2) pull-up/pull-down resistor input or high
impedance input, and (3) NMOS open drain output or
CMOS output.
As secondary functions, P3.0 to P3.3 are assigned
external interrupt functions, P3.3 is assigned a function
that monitors the RC oscillation clock for A/D converter.
