### Pin Change Interrupts
Pin Change Interrupts (PCINTs) can be enabled using pseudo modules. To provide
a low-memory overhead implementation, the PCINTs are grouped into **banks**.
Each banks corresponds to one PCINT on the ATmega (PCINT0, ..., PCINT3).
To enable only a specific bank, simply add `USEMODULE += atmega_pcintN` to your
Makefile. To enable all interrupts you can use `USEMODULE += atmega_pcint`.
In case you want to add a new CPU, simply provide an `atmega_pcint.h` with your
CPU and adapt your Makefile.dep and Makefile.features files.
