Description

Secondary functions of P0.0 to P0.3:

Level-triggered external interrupt input pins.

The change of input signal level causes an interrupt to occur.

Secondary functions of P2.0 to P2.3, P3.0 to P3.3, and P4.0 to P4.3:

Level-triggered external interrupt input pins.

The change of input signal level causes an interrupt to occur.

Secondary functions of P0.0 and P0.1:

Capture circuit trigger input pins.

I

Secondary functions of P3.3:

This pin is assigned the data input of a serial port (SIN).

O

Secondary functions of P4.0:

This pin is assigned the data output of a serial port (SOUT).

O

Secondary functions of P4.1:

This pin is assigned the ready output of a serial port (SPR).

I/O Secondary functions of P4.2:

This pin is assigned the clock I/O of a serial port (SCLK).

Secondary functions of P4.3:

This pin is a monitor output (MON) of an RC oscillation clock

O

(OSCCLK) for an A/D converter and a 400 kHz RC oscillation

clock for a system clock.
