20.1.2
Figure 20-1 shows the configuration of Port 4.
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,
output for each bit in output mode.
bit in input mode.
CS1, RS1, RT1), synchronous serial port pins (SIN0, SCK0, SOUT0), PWM0 output pin (PWM0), and the PWM1
output pin (PWM1) can be used as the secondary functions.
