20.1 Overview
20.1.1
20.1.2
This LSI includes Port 3 (P30 to P35), which is a 6-bit input/output port.
This port can also be used as the RC-ADC (channel 0) oscillation pins (IN0, CS0, RS0, RT0, CRT0, RCM) and the PWM
output pin in secondary and tertiary modes.
For RC-ADC and PWM, see Chapter 24, “RC Oscillation Type A/D converter”, and Chapter 11, “PWM”.
• Allows selection of high-impedance output, P-channel open drain output, N-channel open drain output, or CMOS output
• Allows selection of high-impedance input, input with a pull-down resistor, or input with a pull-up resistor in input
• The RC-ADC (channel 0) oscillation pins (IN0, CS0, RS0, RT0, CRT0, RCM) and the PWM output pin (PWM0) can
