10.6 INT Interrupt
_______
INTi interrupt (i = 0 to 5) is triggered by the edges of external inputs. The edge polarity is selected using bits
IFSR10 to IFSR15 in the IFSR1 register.
________
INT4 share the interrupt vector and interrupt control register with CAN1 successful transmission and SI/O3.
________
INT5 share the interrupt vector and interrupt control register with CAN1 successful reception. To use the
________
INT4 interrupt, set the IFSR16 bit in the IFSR1 register to 1 (INT4). To use the INT5 interrupt, set the
IFSR17 bit in the IFSR1 register to 1 (INT5).
After modifying the IFSR16 or IFSR17 bit, set the corresponding IR bit to 0 (interrupt not requested) before
enabling the interrupt.
Figure 10.11 shows Registers IFSR0 and IFSR1.
