**Overview**
The custom functions subsystem is meant for implementing custom tightly-coupled co-processors or interfaces.

IT provides up to 16384 32-bit memory-mapped read/write registers (`REG`, see register map below) that can be
accessed by the CPU via normal load/store operations. The actual functionality of these register has to be
defined by the hardware designer. Furthermore, the CFS provides two IO conduits to implement custom on-chip
or off-chip interfaces.
