Description
Technology Ability Field [2]
Value Description
1 The Ethernet Controller supports the 100Base-TX half-duplex
signaling protocol. If software wants to ensure that this mode
is not used, this bit can be cleared and auto-negotiation
re-initiated with the RANEG bit in the MR0 register.
0 The Ethernet Controller does not support the 100Base-TX
half-duplex signaling protocol.
1
Technology Ability Field [1]
Value Description
1 The Ethernet Controller supports the 10BASE-T full-duplex
signaling protocol. If software wants to ensure that this mode
is not used, this bit can be cleared and auto-negotiation
re-initiated with the RANEG bit in the MR0 register.
0 The Ethernet Controller does not support the 10BASE-T
full-duplex signaling protocol.
