Example text

Set Timer 1 subpriority level, T1IS (if required). Enable Timer 1 interrupts, T1IE (bit 4 in IEC0). Enable Timer 1, ON (bit 15 in T1CON). Write the ISR. Enable interrupts. Configuring external interrupt 0 The PIC32 microcontroller supports four external interrupts inputs, INT0–INT3. Interrupts can be recognised on either the low-to-high or the high-to-low transition of the interrupt pin, selected by INTCON. External interrupt flag INT0IF must be cleared before an interrupt can be accepted. In addition, INT0IE bit must be set to enable interrupts from external interrupt INT0 pin.

In multiple vectored interrupt operations, each interrupting device has its unique ISR address. (In actual fact, PIC32 microcontrollers have 96 interrupt sources and only 64 vectors. ) PIC32 microcontrollers support seven levels of interrupt priority (ipl1–ipl7). If more than one interrupt occurs at the same time, then the one with higher priority is serviced first. If while servicing an interrupt, a lower-priority interrupt occurs, then it will be ignored by the processor. In addition to standard interrupt priority levels, the PIC32 microcontrollers support four levels of subpriorities.

Interrupts can be recognised on either the low-to-high or the high-to-low transition of the interrupt pin, selected by INTCON. External interrupt flag INT0IF must be cleared before an interrupt can be accepted. In addition, INT0IE bit must be set to enable interrupts from external interrupt INT0 pin. In multi-interrupt operations, it is recommended to set the priority and subpriority levels of the interrupt. The steps in configuring the external interrupt 0 are given as follows: • • • • • • • • Configure for single vector or multivector interrupt mode (bit 12, INTCON).
