1 = Advertise that the DTE (MAC) has implemented both the optional MAC control sublayer and the pause function as specified in clause 31 and annex 31B of 802.3u. | |||
0 = No MAC based full duplex flow control | |||
10 | PAUSE | 0, RW | PAUSE Support for Full Duplex Links: |
The PAUSE bit indicates that the device is capable of providing the symmetric PAUSE functions as defined in Annex 31B. | |||
Encoding and resolution of PAUSE bits is defined in IEEE 802.3 Annex 28B, Tables 28B-2 and 28B-3, respectively. Pause resolution status is reported in PHYCR[13:12]. | |||
1 = Advertise that the DTE (MAC) has implemented both the optional MAC control sublayer and the pause function as specified in clause 31 and annex 31B of 802.3u. | |||
0= No MAC based full duplex flow control | |||
9 | T4 | 0, RO/P | 100BASE-T4 Support: |
