11.5.10 FIFO Receive Start Register (FRSR)
The FRSR register,
FIFO. FRSR marks the boundary between the transmit and receive FIFOs. The transmit FIFO uses
addresses from TFSR to FRSR - 4. The receive FIFO uses addresses from FRSR to FRBR - 4. The value
in this register must be added to MBAR + 0x800 to determine the absolute address.
FRSR needs to be written only to change the default value.
