This is the default value. EXPFIFO is also set to this value when enhanced features
are disabled.
In this mode, the FIFO interface acts identically to the Prometheus. Even though the
ELEKTRA is using an external FIFO, the FPGA must track the depth manually to
provide support for programmable threshold and depth tracking.

Expanded FIFO is enabled. This disables dynamic threshold and depth tracking,
instead using boards with OVF, FF, HF and EF for tracking. Please refer to base+6
