18 Port 1
18.1 Overview
This LSI incorporates a 2-bit input port, Port 1 (P10, P11).
Port 1 can have a high-speed oscillation pin or an external clock input pin. When the port is used as a high-speed
oscillation pin, the P11 pin functions as an output pin if crystal/ceramic oscillation mode is selected with the OSCM1–0
bits of the FCON0 register.
For high-speed oscillation and external clock input, see Chapter 6, “Clock Generation Circuit”.
18.1.1 Features
•
Allows selection of high-impedance input, input with a pull-down resistor, or input with a pull-up resistor for each bit.
•
Allows selection of high-impedance output, P-channel open drain output, N-channel open drain output, or CMOS
output in output mode for each bit.
•
Allows selection of a high-speed crystal/ceramic oscillation pin or an external clock input pin.
