Description
Receive Data Valid.
RVAL indicates the validity of the receive
data signals. RVAL is Low between
transfers and assertion of RSX. It is also
Low when the IXF1104 MAC pauses a
transfer due to an empty receive FIFO.
When a transfer is paused by holding RENB
High, RVAL holds its value unchanged,
although no new data is present on
RDAT[31:0] until the transfer resumes.
When RVAL is High, the RDAT[31:0],
RMOD[1:0], RSOP, REOP, and RERR
signals are valid. When RVAL is Low, the
RDAT[31:0], RMOD[1:0], RSOP, REOP, and
RERR signals are invalid and must be
disregarded.
The RSX signal is valid only when RVAL is
Low.
32-bit Multi-PHY mode: RVAL_0 covers all
receive bits.
4 x 8 Single-PHY mode: The RVAL_0:3 bits
correspond to the per-port data and control
signals.
Receive Start of Packet.
RSOP indicates the start of a packet when
asserted with RVAL.
32-bit Multi-PHY mode: RSOP_0 covers all
32 bits.
4 x 8 Single-PHY mode: The RSOP_0:3 bits
correspond to the RDAT[7:0]_n channels.
