The microcontroller provides the maskable external interrupts INTPn and one
non-maskable interrupt (NMI).
INTPn can be configured to generate interrupts upon edges or levels, the NMI
can be set up to react on edges.
INTM0 to INTM3 - External interrupt configuration register
External interrupt function is configured by the registers INTM0…INTM3.
The register bits ELSELn, ESELn1 and ESELn0 configure the INTPn interrupt
function:
