17. Port 4
17.1 Overview
17.1.1 Features
17.1.2 Configuration
This LSI includes Port 4 (P40 to P47) which is an 8-bit input/output port.
This Port 4 can have the UART, RC-ADC, synchronous serial port, and PWM output functions as the secondary and
tertiary functions.
For the UART, see Chapter 13, "UART." For the RC-ADC, see Chapter 21, "RC Oscillation Type A/D Converter." For
the synchronous serial port, see Chapter 12, "Synchronous Serial Port." For the PWM, see Chapter 10, "PWM."
Figure 17-1 shows the configuration of Port 4.
