18.3 Description of Operation
18.3.1
18.3.2
For each pin of Port 1, one of high-impedance input mode, input mode with a pull-down resistor, and input mode with
a pull-up resistor can be selected by setting the Port 1 control registers 0 and 1 (P1CON0 and P1CON1). At system
reset, high-impedance input mode is selected as the initial state.
The input level of the Port 1 pin can be read by reading the Port 1 data register (P1D).
An external clock input pin is assigned to Port 1 as a secondary function. Supply the clock to P10 pin and select the
external clock input mode by setting the OSCM0 bit of frequency control register 0 (FCON0) to “1”.
Note:
No port mode register is provided for switching between the primary function and the secondary function of Port 1.
When using the Port 1 pins as the external clock input, pin mode is switched according to the values set in the OSCM0
bit of the FCON0 register.
See Chapter 6, “Clock Generation Circuit,” for the details of the FCON0 register and the external clock input.
