39 / 72 page ![]() RTL8211F(I)/RTL8211FD(I) Datasheet Integrated 10/100/1000M Ethernet Transceiver 32 Track ID: JATR-8275-15 Rev. 1.1 8.4.2. BMSR (Basic Mode Status Register, Address 0x01) Table 23. BMSR (Basic Mode Status Register, Address 0x01) Bit Name Type Default Description 1.15 100Base-T4 RO 0 100Base-T4 Capability. The RTL8211F(I)/RTL8211FD(I) does not support 100Base-T4 mode. This bit should always be 0. 1.14 100Base-TX (full) RO 1 100Base-TX Full Duplex Capability. 1: Device is able to perform 100Base-TX in full duplex mode 0: Device is not able to perform 100Base-TX in full duplex mode 1.13 100Base-TX (half) RO 1 100Base-TX Half Duplex Capability. 1: Device is able to perform 100Base-TX in half duplex mode 0: Device is not able to perform 100Base-TX in half duplex mode 1.12 10Base-T (full) RO 1 10Base-T Full Duplex Capability. 1: Device is able to perform 10Base-T in full duplex mode. 0: Device is not able to perform 10Base-T in full duplex mode. 1.11 10Base-T (half) RO 1 10Base-T Half Duplex Capability. 1: Device is able to perform 10Base-T in half duplex mode 0: Device is not able to perform 10Base-T in half duplex mode 1.10 10Base-T2 (full) RO 0 10Base-T2 Full Duplex Capability. The RTL8211F(I)/RTL8211FD(I) does not support 10Base-T2 mode and this bit should always be 0. 1.9 10Base-T2 (half) RO 0 10Base-T2 Half Duplex Capability. The RTL8211F(I)/RTL8211FD(I) does not support 10Base-T2 mode. This bit should always be 0. 1.8 1000Base-T Extended Status RO 1 1000Base-T Extended Status Register. 1: Device supports Extended Status Register 0x0F (15) 0: Device does not support Extended Status Register 0x0F This register is read-only and is always set to 1. 1.7 Uni-directional ability RO 1 Uni-directional ability. 1: PHY able to transmit from RGMII without linkok 0: PHY not able to transmit from RGMII without linkok 1.6 Preamble Suppression RO 1 Preamble Suppression Capability (Permanently On). The RTL8211F(I)/RTL8211FD(I) always accepts transactions with preamble suppressed. 1.5 Auto-Negotiation Complete RO 0 Auto-Negotiation Complete. 1: Auto-Negotiation process complete, and contents of registers 5, 6, 8, and 10 are valid 0: Auto-Negotiation process not complete 1.4 Remote Fault RC, LH 0 Remote Fault. 1: Remote fault condition detected (cleared on read or by reset). Indication or notification of remote fault from Link Partner 0: No remote fault condition detected 1.3 Auto-Negotiation Ability RO 1 Auto Configured Link. 1: Device is able to perform Auto-Negotiation 0: Device is not able to perform Auto-Negotiation |
