16.1 Overview
16.1.1 Features
16.1.2 Configuration
16.1.3 List of Pins
This LSI includes Port 3 (P30 to P35), which is a 6-bit input/output port.
Furthermore, the oscillation pins (IN0, CS0, RS0, RT0, RCT0, and RCM) for the RC-ADC (Channel 0) are provided as
the secondary function mode.
For the RC-ADC, see Chapter 21, “RC Oscillation Type A/D Converter”.
Figure 16-1 shows the configuration of Port 3.
