14.3 Description of Operation
14.3.1 External Interrupt / Secondary Function
14.3.2 Interrupt Request
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).
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, any of the maskable P00 to P04 interrupts (P00INT to P04INT) occurs.
Figure 14-2 shows the P00 to P04 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 P04 interrupt generation timing in rising-edge
interrupt mode with sampling.
The Port 0 pins (P00, P01, P02, P03, P04) can be used for P00 to P04 interrupts (P00INT to P04INT). The P00 to P04
interrupts are maskable and interrupt enable or disable can be selected. For interrupts, see Chapter 5, "Interrupt."
The P00 and P01 pins can be used as the trigger input to the capture circuit, the P02 pin as the RXD0 input to the
UART0, and the P04 pin as the external clock input to the timers and the PWM.
For the capture function, see Chapter 8, "Capture." For the UART function, see Chapter 13, "UART." For the timer
function, see Chapter 9, "Timer." For the PWM function, see Chapter 10, "PWM."
