14. Port 3
14.1 Overview
This LSI includes Port 3 (P35), which is a 1-bit input/output port.
Furthermore, the oscillation pin (RCM) for the RC-ADC (Channel 1) are provided as the secondary function mode.
For the RC-ADC, see Chapter 17, “RC Oscillation Type A/D Converter”.
14.1.1 Features
•
Allows selection of high-impedance output, P-channel open drain output, N-channel open drain output, or CMOS
output for each bit in output mode.
•
Allows selection of high-impedance input, input with a pull-down resistor, or input with a pull-up resistor for
each bit in input mode.
•
The oscillation pin (RCM) for the RC-ADC (Channel 1) are available as the secondary function mode.
