Interrupts
INT Interrupt
Figure 1.9.10. Interrupt request cause select register
INT0, INT1, INT3 to INT5 are triggered by the edges of external inputs. The edge polarity of the interrupt is
selected using the polarity select bit in the interrupt control registers, 0044
005E
To generate interrupts on both rising and falling edges, set the INTi interrupt polarity switching bit of the
interrupt request cause select register (035F
generated regardless of the value set in the polarity select bit of the corresponding interrupt control regis-
ter.
Figure 1.9.10 shows the Interrupt request cause select register.
