19.1 Overview
19.1.1
19.1.2
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 23, “RC Oscillation Type A/D converter”, and Chapter 10, “PWM”.
• 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 in input
