AX88140A
MF - Multicast Frame Indicates that this frame is a multicast address.
This field is valid only when last descriptor (RDES0<8>) is set.
PRELIMINARY
ASIX ELECTRONICS CORPORATION
32
10
1
Indicates that this descriptor contains the first buffer of a
frame.
9
FS - First Descriptor
0
Indicates that this descriptor is the middle or last buffer of
a frame.
Indicates that the buffers pointed to by this descriptor, are
the last buffers
Indicates that this descriptor is the middle or first buffer of
a frame.
1
8
LS - Last Descriptor
0
7
TL - Frame Too Long. Frame length grater then 1518 bytes. Active high.
This field is valid only when last descriptor (RDES0<8>) is set.
6
CS - Collision Seen. This is a late collision.
This field is valid only when last descriptor (RDES0<8>) is set.
5
4
Reserved.--Written as “0” for future compatibility concern.
RW - Receive Watchdog time expire. Active high.
This field is valid only when last descriptor (RDES0<8>) is set.
3
2
RE - Report on MII Error. Active high.
DB - Dribbling Bit Active high.
If set, and CRC error (RDES0<1>) is reset, then the packet is valid.
CE - CRC Error. Active high.
This field is valid only when last descriptor (RDES0<8>) is set.
FIFO Overrun. Active high.

Tab - 32 Receive Descriptor 0
5.2.2 Receive Descriptor 1 (RDES1)
FIELD
31:11
Reserved.--Written as “0” for future compatibility concern.
10:0
RBS - Receive Data Buffer Size
Indicates the size in bytes of the data buffer. If this field is 0, the AX88140A ignores this buffer.
The buffer size must be a multiple of 4.
DESCRIPTION
Tab - 33 Receive Descriptor 1
5.2.3 Receive Descriptor 2 (RDES2)
FIELD
31:0
Data Buffer Pointer
Indicates the physical address of data buffer. The buffer must be long-word-aligned (RDES2<1:0>=00).
DESCRIPTION
Tab - 34 Receive Descriptor 2
5.2.4 Receive Descriptor 3 (RDES3)
FIELD
31:0
Address Pointer
Indicates the physical address of next descriptor. The address must be long-word aligned (RDES3<1:0>=00).
