3.6 INTERRUPTS
A list of interrupt sources is given in
Table 4
below,
together with relevant details for each source. In-
terrupts are serviced according to their order of pri-
ority, starting with I0, which has the highest priori-
ty, and so to I12, which has the lowest priority.
The following list describes the origins for each in-
terrupt level:
– I0 connected to Ports PA0-PA7, PB0-PB1
– I1 connected to CAN
– I2 connected to Power Diagnostics
– I3 connected to Output Compare of Timer 1
– I4 connected to Input Capture of TImer 1
– I5 connected to Timer 1 Overflow
– I6 connected to Output Compare of Timer 2
– I7 connected to Input Capture of TImer 2
– I8 connected to Timer 2 Overflow
– I9 connected to ADC End Of Conversion
– I10 connected to PWM 1 Overflow
– I11 connected to PWM 2 Overflow
– I12 connected to EEPROM
Exit from Halt mode may only be triggered by an
External Interrupt on one of the following ports:
PA0-PA7 (I0), PB0-PB1 (I0), or by an Internal In-
terrupt coming from CAN peripheral (I1).
If more than one input pin of a group connected to
the same interrupt line are selected simultaneous-
ly, the OR of this signals generates the interrupt.
