Bank 18 Receive Status Register (0x04): RXSR
This register indicates the status of the current received frame and mirrors the Receive Status word of the Receive Frame
in the RXQ.
Bit
Default Value
R/W
Description
15
-
RO
RXFV Receive Frame Valid
When set, it indicates that the present frame in the receive packet memory is valid.
The status information currently in this location is also valid.
When clear, it indicates that there is either no pending receive frame or that the
current frame is still in the process of receiving.
14-10
-
RO
Reserved
9-8
-
RO
RXSPN Receive Source Port Number
When bit is set, this field indicates the source port where the packet was received.
(Setting bit 9 = 0 and bit 8 = 1 indicates the packet was received from port 1. Setting
bit 9 = 1 and bit 8 = 0 indicates that the packet was received from port 2. Valid port is
either port 1 or port 2.
7
-
RO
RXBF Receive Broadcast Frame
When set, it indicates that this frame has a broadcast address.
6
-
RO
RXMF Receive Multicast Frame
When set, it indicates that this frame has a multicast address (including the broadcast
address).
5
-
RO
RXUF Receive Unicast Frame
When set, it indicates that this frame has a unicast address.
4
-
RO
Reserved
3
-
RO
RXFT Receive Frame Type
When set, it indicates that the frame is an Ethernet-type frame (frame length is greater
than 1500 bytes).
When clear, it indicate that the frame is an IEEE 802.3 frame.
This bit is not valid for runt frames.
2
-
RO
RXTL Receive Frame Too Long
When set, it indicates that the frame length exceeds the maximum size of 1916 bytes.
Frames that are too long are passed to the host only if the pass bad frame bit is set
(bit 9 in RXCR register)
Note: Frame too long is only a frame length indication and does not cause any frame
truncation.
1
-
RO
RXRF Receive Runt Frame
When set, it indicates that a frame was damaged by a collision or premature
termination before the collision window has passed. Runt frames are passed to the
host only if the pass bad frame bit is set (bit 9 in RXCR register).
0
-
RO
RXCE Receive CRC Error
When set, it indicates that a CRC error has occurred on the current received frame. A
CRC error frame is passed to the host only if the pass bad frame bit is set (bit 9 in
RXCR register).
