R_BOUND
17.4.21 FIFO Receive Start Register (FRSR)
FRSR indicates the starting address of the receive FIFO. FRSR marks the boundary between the transmit
and receive FIFOs. The transmit FIFO uses addresses from the start of the FIFO to the location four bytes
before the address programmed into the FRSR. The receive FIFO uses addresses from FRSR to FRBR
inclusive.
Hardware initializes the FRSR register at reset. FRSR only needs to be written to change the default value.
17.4.22 Receive Descriptor Ring Start Register (ERDSR)
ERDSR points to the start of the circular receive buffer descriptor queue in external memory. This pointer
must be 32-bit aligned; however, it is recommended it be made 128-bit aligned (evenly divisible by 16).
This register is not reset and must be initialized prior to operation.
