network_status (GEM) Register Bit-Field Summary
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
Reserved | 31:8 | roRead-only | 0x0 | Reserved, read as zero, ignored on write. |
lpi_indicate_pclk | 7 | roRead-only | 0x0 | LPI Indication - Low power idle has been detected on receive. This bit is set when LPI is detected and reset when normal idle is detected. An interrupt is generated when the state of this bit changes. |
pfc_negotiate_pclk | 6 | roRead-only | 0x0 | Set when PFC Priority Based Pause has been negotiated. |
mac_pause_tx_en | 5 | roRead-only | 0x0 | PCS auto-negotiation pause transmit resolution. |
mac_pause_rx_en | 4 | roRead-only | 0x0 | PCS auto-negotiation pause receive resolution |
mac_full_duplex | 3 | roRead-only | 0x0 | PCS auto-negotiation duplex resolution. Set to one if the resolution function determines that both devices are capable of full duplex operation. If zero half-duplex operation is possible as long as bit 0 (PCS link state) is also one. |
man_done | 2 | roRead-only | 0x1 | The PHY management logic is idle (i.e. has completed). |
mdio_in | 1 | roRead-only | 0x0 | Returns status of the mdio_in pin. |
pcs_link_state | 0 | roRead-only | 0x0 | Returns status of PCS link state. If auto-negotiation is disabled this returns the synchronisation status. If auto-negotiation is enabled it is set in the LINK_OK state as long as a compatible duplex mode is resolved, it is always set in the LINK_OK state in SGMII mode. |
