Description
Checksum Calculation
Specifies whether to perform automatic calculation
(hardware calculation) of the checksum of the receive
frame data unit.
0: Checksum is not automatically calculated
1: Checksum is automatically calculated
Note that the checksum calculation of a frame with a
VLAN tag is not supported.
Reserved
This bit is always read as 0. The write value should
always be 0.
Data Padding
0: Padding is inserted to data less than 60 bytes so it is
1: Padding is not inserted to data less than 60 bytes
PAUSE Frame Reception with TIME = 0
0: Reception of a PAUSE frame whose TIME
1: Reception of a PAUSE frame whose TIME
transmitted as 60-byte data
and it is transmitted without changes
parameter value is 0 is disabled
parameter value is 0 is enabled
