For receive, the packet receive status always reflects the receive status of the packet received in the current RX packet
memory (see Table 7). The RXSR register indicates the status of the current received frame.
Bit
Description
15
RXFV Receive Frame Valid
When bit is set, indicates that the present frame in the receive packet memory is valid and
received from MAC/PHY. The status information currently in this location is also valid.
When bit is reset, indicates that there is either no pending receive frame or current frame is
still in the process of receiving and has not completed yet.
14-10
Reserved
9-8
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
RXBF Receive Broadcast Frame
When bit is set, indicates that this frame has a broadcast address.
6
RXMF Receive Multicast Frame
When bit is set, it indicates that this frame has a multicast address (including the broadcast
address).
5
RXUF Receive Unicast Frame
When bit is set, indicates that this frame has a unicast address.
4
Reserved
3
RXFT Receive Frame Type
When bit is set, indicates that the frame is an Ethernet-type frame (frame length is greater
than 1500 bytes). When clear, indicate that the frame is an IEEE 802.3 frame.
This bit is not valid for runt frames.
2
RXTL Receive Frame Too Long
When bit is set, indicates that the frame length exceeds the maximum size of 1518 bytes.
Frames too long are passed to the host only if the pass bad frame bit is set.
Note: Frame too long is only a frame length indication and does not cause any frame
truncation.
1
RXRF Receive Runt Frame
When bit is set, 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.
0
RXCE Receive CRC Error
When bit is set, indicates that a CRC error has occurred on the current received frame. CRC
error frame are passed to the host only if the pass bad frame bit is set.
Table 7. FRXQ Packet Receive Status
Table 8 gives the format of the RX byte count field.
