22.1 Overview
22.1.1
22.1.2
This LSI includes Port 4 (P40 to P47) which is an 8-bit input/output port.
This port can have the I2C bus, RC-ADC, synchronous serial port, and PWM output functions as secondary and
tertiary functions.
See the following chapters for reference:
• Allows selection of high-impedance output, P-channel open drain output, N-channel open drain output, or CMOS
• Allows selection of high-impedance input, input with a pull-down resistor, or input with a pull-up resistor for each
• The P44 and P45 pins can be used as external clock input pins for the timer and PWM.
• The I2C bus interface pins (SDA, SCL), UART pins (RXD0, TXD0), RC-ADC (channel 1) oscillation pins (IN1,

CS1, RS1, RT1), synchronous serial port pins (SIN0, SCK0, SOUT0), and PWM output pin (PWM0) can be used as
the secondary functions.
