21 / 65 page ![]() IP101G Data Sheet Default value Bit Name Description/Usage (h): 3100 Register 0 : Control Register 0=normal operation 9 Restart Auto- Negotiation This bit allows the auto-negotiation function to be reset. 1 = restart auto-negotiation 0 = normal operation 0, RW/SC 8 Duplex Mode This bit sets the duplex mode if auto-negotiation is disabled (bit 12=0) 1 = full duplex 0 = half duplex After completing auto-negotiation, this bit will reflect the duplex status.(1: Full duplex, 0: Half duplex) 1, RW 7 Collision Test 1=enable COL signal test 0=disable COL signal test 0,RW 6:0 Reserved 0, RO Bit Name Description/Usage Default value (h): 7849 Register 1 : Status Register 15 100Base-T4 1 = enable 100Base-T4 support 0 = suppress 100Base-T4 support 0, RO 14 100Base-TX Full Duplex 1 = enable 100Base-TX full duplex support 0 = suppress 100Base-TX full duplex support 1, RO 13 100BASE-TX Half1 = enable 100Base-TX half duplex support Duplex 0 = suppress 100Base-TX half duplex support 1, RO 12 10Base-T Full Duplex 1 = enable 10Base-T full duplex support 0 = suppress 10Base-T full duplex support 1, RO 11 10_Base-T Half1 = enable 10Base-T half duplex support Duplex 0 = suppress 10Base-T half duplex support 1, RO 10:7 Reserved 0, RO 6 MF Preamble Suppression The IP101G will accept management frames with preamble suppressed. The IP101G accepts management frames without preamble. A Minimum of 32 preamble bits is required for the first SMI read/write transaction after reset. One idle bit is required between any two management transactions as per IEEE802.3u specifications 1, RO 5 Auto- Negotiation Complete 1 = auto-negotiation process completed 0 = auto-negotiation process not completed 0, RO 4 Remote Fault 1 = remote fault condition detected (cleared on read) 0 = no remote fault condition detected 0, RO/LH 3 Auto- Negotiation 1 = able to perform auto-negotiation 0 = unable to perform auto-negotiation 1, RO 2 Link Status 1 = valid link established 0 = no valid link established 0, RO/LL 1 Jabber Detect 1 = jabber condition detected 0 = no jabber condition detected 0, RO/LH 0 Extended Capability 1 = extended register capability 0 = basic register capability only 1, RO 21/65 January 14, 2014 Copyright © 2011, IC Plus Corp.
