Figure 20-16. External interrupt pad diagram
3
20 interrupts in 100-pin LQFP.
Each interrupt can be enabled or disabled independently. This can be performed using the IRER. A pad
defined as an external interrupt can be configured to recognize interrupts with an active rising edge, an
active falling edge or both edges being active. A setting of having both edge events disabled is reserved
and should not be configured.
The active EIRQ edge is controlled through the configuration of the registers IREER and IFEER.
Each external interrupt supports an individual flag in the Interrupt Status Flag Register (ISR). The bits in
the ISR[EIF] field are cleared by writing a 1 to them; this prevents inadvertent overwriting of other flags
in the register.
