38 / 61 page ![]() High Performance Single Chip Low Power 10/100 Ethernet Physical Layer Transceiver (PHY) Datasheet Rev. 0.8 (11-16-04) 38 SMSC LAN83C185 DATASHEET Table 5.40 Register 6 - Auto Negotiation Expansion ADDRESS NAME DESCRIPTION MODE DEFAULT 6.15:5 Reserved RO 0 6.4 Parallel Detection Fault 1 = fault detected by parallel detection logic 0 = no fault detected by parallel detection logic RO/ LH 0 6.3 Link Partner Next Page Able 1 = link partner has next page ability 0 = link partner does not have next page ability RO 0 6.2 Next Page Able 1 = local device has next page ability 0 = local device does not have next page ability RO 0 6.1 Page Received 1 = new page received 0 = new page not yet received RO/ LH 0 6.0 Link Partner Auto- Negotiation Able 1 = link partner has auto-negotiation ability 0 = link partner does not have auto-negotiation ability RO 0 Table 5.41 Register 16 - Silicon Revision ADDRESS NAME DESCRIPTION MODE DEFAULT 16.15:10 Reserved RO 0 16.9:6 Silicon Revision Four-bit silicon revision identifier. RO 0001 16.5:0 Reserved RO 0 Table 5.42 Register 17 - Mode Control/Status ADDRESS NAME DESCRIPTION MODE DEFAULT 17.15 Reserved Write as 0; ignore on read. RW 0 17.14 FASTRIP 10Base-T fast mode: 0 = normal operation 1 = Reserved Must be left at 0 RW, NASR 0 17.13 EDPWRDOWN Enable the Energy Detect Power-Down mode: 0 = Energy Detect Power-Down is disabled 1 = Energy Detect Power-Down is enabled RW 0 17.12 Reserved Write as 0, ignore on read RW 0 17.11 LOWSQEN The Low_Squelch signal is equal to LOWSQEN AND EDPWRDOWN. Low_Squelch = 1 implies a lower threshold (more sensitive). Low_Squelch = 0 implies a higher threshold (less sensitive). RW 0 17.10 MDPREBP Management Data Preamble Bypass: 0 – detect SMI packets with Preamble 1 – detect SMI packets without preamble RW 0 17.9 Reserved Reserved Must be left at 0 RW 0 |
