28 / 66 page RTL8100B(L) Datasheet Single-Chip 10/100 Ethernet Controller w/Power Management 22 Track ID: JATR-1076-21 Rev. 1.5 6.13. CONFIG 3: Configuration Register3 (Offset 0059h, R/W) Bit R/W Symbol Description 7 R GNTSel Gnt Select: Select the Frame’s asserted time after the Grant signal has been asserted. The Frame and Grant are the PCI signals. 0: No delay 1: delay one clock from GNT assertion. 6 R/W PARM_En Parameter Enable: (Used in 100Mbps mode only) This set to 0 and the 9346CR register EEM1=EEM0=1 will enable the PHY1_PARM, PHY2_PARM,and TW_PARMregisterstobewrittenviasoftware. This set to 1 will allow parameters to be auto-loaded from the 93C46 and disable writing to the PHY1_PARM, PHY2_PARM and TW_PARM registers via software. The PHY1_PARM and PHY2_PARM can be auto-loaded from the EEPROM in this mode. The parameter auto-load process is executed every time the Link is OK in 100Mbps mode. 5 R/W Magic Magic Packet: This bit is valid when the PWEn bit of the CONFIG1 register is set. The RTL8100B(L) will assert the PMEB signal to wakeup the operating system when the Magic Packet is received. Once the RTL8100B(L) has been enabled for Magic Packet wakeup and has been put into adequate state, it scans all incoming packets addressed to the node for a specific data sequence, which indicates to the controller that this is a Magic Packet frame. A Magic Packet frame must also meet the basic requirements of: Destination address + Source address + data + CRC The destination address may be the node ID of the receiving station or a multicast address, which includes the broadcast address. The specific sequence consists of 16 duplications of 6 byte ID registers, with no breaks or interrupts. This sequence can be located anywhere within the packet, but must be preceded by a synchronization stream, 6 bytes of FFh. The device will also accept a multicast address, as long as the 16 duplications of the IEEE address match the address of the ID registers. If the Node ID is 11h 22h 33h 44h 55h 66h, then the magic frame’s format is similar to the following: Destination address + source address + MISC + FF FF FF FF FF FF + MISC + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + MISC + CRC 4 R/W LinkUp Link Up: This bit is valid when the PWEn bit of CONFIG1 register is set. The RTL8100B(L), in adequate power state, will assert the PMEB signal to wakeup the operating system when the cable connection is re-established. 3-1 - - Reserved 0 R FBtBEn Fast Back to Back Enable: Set to 1 to enable Fast Back to Back. |
