17.3 Description of Operation
17.3.1
17.3.2
For each pin of Port 0, the setting of the Port 0 control registers 0 and 1 (P0CON0 and P0CON1) allows selection of
high-impedance input mode, input mode with a pull-down resistor, or input mode with a pull-up resistor.
High-impedance input mode is selected at system reset.
The pin level of Port 0 can be read by reading the Port 0 data register (P0D)
The Port 0 pins (P00, P01, P02, P03) can be used for P00 to P03 interrupts (P00INT to P03INT). The P00 to P03
interrupts are maskable and interrupt enable or disable can be selected. For details of interrupts, see Chapter 5,
“Interrupts”.
The P00 and P01 pins can be used as the trigger input for the capture circuit and the P02 pin can be used as the RXD0
input pin of UART0.
For the capture function and the UART function, see Chapter 8, “Capture,” and Chapter 14, “UART,” respectively.
When an interrupt edge selected with the external interrupt control register 0, 1, or 2 (EXICON0, EXICON1, or
EXICON2) occurs at a Port 0 pin, a maskable P00 (P01, P02, or P03) interrupt (P00INT, P01INT, P02INT, or P03INT).
Figure 17-2 shows the P00 to P03 interrupt generation timing in rising-edge interrupt mode, in falling-edge interrupt
mode, and in both-edge interrupt mode without sampling and the P00 to P03 interrupt generation timing in rising-edge
interrupt mode with sampling.
