Bit is self-clearing. For best results, when setting this bit do not set other bits in this register. The configuration (as described in Section 5.3.9.2) is set from the register bit values, and not from the mode pins. RW/ SC 0 0.14 Loopback 1 = loopback mode, 0 = normal operation RW 0 0.13 Speed Select 1 = 100Mbps, 0 = 10Mbps. Ignored if Auto Negotiation is enabled (0.12 = 1). RW Set by MODE[2:0] bus 0.12 Auto- Negotiation Enable 1 = enable auto-negotiate process (overrides 0.13 and 0.8) 0 = disable auto-negotiate process RW Set by MODE[2:0] bus 0.11 Power Down 1 = General power down mode, 0 = normal operation RW 0 0.10 Isolate 1 = electrical isolation of transceiver from MII 0 = normal operation RW 0 0.9 Restart Auto- Negotiate 1 = restart auto-negotiate process 0 = normal operation. Bit is self-clearing. RW/ SC 0 0.8 Duplex Mode 1 = Full duplex, 0 = Half duplex. Ignored if Auto Negotiation is enabled (0.12 = 1). RW Set by MODE[2:0] bus 0.7 Collision Test 1 = enable COL test, 0 = disable COL test RW 0 0.6:0 Reserved RO 0 Table 5.22 Register 1 - Basic Status ADDRESS NAME DESCRIPTION MODE DEFAULT 1.15 100Base-T4 1 = T4 able, 0 = no T4 ability RO 0 1.14 100Base-TX Full Duplex 1 = TX with full duplex, 0 = no TX full duplex ability RO 1 1.13 100Base-TX Half Duplex 1 = TX with half duplex, 0 = no TX half duplex ability RO 1 1.12 10Base-T Full Duplex 1 = 10Mbps with full duplex 0 = no 10Mbps with full duplex ability RO 1 1.11 10Base-T Half Duplex 1 = 10Mbps with half duplex 0 = no 10Mbps with half duplex ability RO 1 1.10:6 Reserved 1.5 Auto-Negotiate Complete 1 = auto-negotiate process completed 0 = auto-negotiate process not completed RO 0 |
