17.1 Overview

17.1.2
17.1.3
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 as a secondary function. 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”.
• Allows selection of high-impedance input mode, input mode with a pull-down resistor, or input mode with a pull-up
• Allows selection of a high-speed crystal/ceramic resonator pin or an external clock input pin as a secondary function.
Figure 17-1 shows the configuration of Port 1.
