18.1.3
This LSI incorporates a 2-bit input port, Port 1 (P10, P11).
Port 1 can have an external clock input pin as a secondary function.
For the 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 to have an external clock input pin as a secondary function.
Figure 18-1 shows the configuration of Port 1.
