Clocking

GFC-100 has a single clock domain, that is used for clocking all internal registers.

Synchronous interfaces

The GFC-100 AHB‑Lite slave, APB, and GFB interfaces are expected to run on the same clock.

Asynchronous interfaces

The GFC-100 Q‑Channel and P‑Channel interfaces might be clocked asynchronously. Therefore, these interfaces have internal synchronizers.
