Description
Reception Enable
If a switch is made from receiving function enabled (RE
= 1) to disabled (RE = 0) while a frame is being
received, the receiving function will be enabled until
reception of the corresponding frame is completed.
0: Receiving function is disabled
1: Receiving function is enabled
Transmission Enable
If a switch is made from transmitting function enabled
(TE = 1) to disabled (TE = 0) while a frame is being
transmitted, the transmitting function will be enabled
until transmission of the corresponding frame is
completed.
0: Transmitting function is disabled
1: Transmitting function is enabled
Reserved
This bit is always read as 0. The write value should
always be 0.
Internal Loop Back Mode
Specifies loopback mode in the GETHER.
0: Normal data transmission/reception is performed
1: Data loopback is performed inside the E-MAC in the
Reserved
This bit is always read as 0. The write value should
always be 0.
Duplex Mode
Specifies the GETHER transfer method.
0: Half-duplex transfer is specified
1: Full-duplex transfer is specified
GETHER when DM = 1
