-### 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.
