Basic Functions (continued)
I
Ports
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 functions, an external interrupt and
capture circuit trigger input are allocated.
If P2.0 to P2.3 are set to "H" level, the device enters system reset
mode.

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 a secondary function, an external interrupt is
allocated to P3.0 and an event counter is allocated to P3.1.
