9 / 75 page ![]() RTL8111B/RTL8168B Registers Datasheet Integrated Gigabit Ethernet Controller for PCI Express 3 Track ID: JATR-1076-21 Rev. 1.0 Offset Tag RW Description 0048h-004Bh TCTR RW Timer CounT Register: This register contains a 32-bit general-purpose timer. Writing any value to this 32-bit register will reset the original timer and begin the count from zero. This counter is based on the PCI clock connected. For PCI-E NICs, the internal PCI clock is 125MHz. Therefore, the unit of TCTR of the RTL8111B/RTL8168B is 8ns. 004Ch-004Fh - - Reserved 0050h 9346CR RW 93C46 Command Register 0051h CONFIG0 RW Configuration Register 0 0052h CONFIG1 RW Configuration Register 1 0053h CONFIG2 RW Configuration Register 2 0054h CONFIG3 RW Configuration Register 3 0055h CONFIG4 RW Configuration Register 4 0056h CONFIG5 RW Configuration Register 5 0057h - - Reserved 0058h-005Bh TimerInt R /W Timer Interrupt Register. Once having written a non-zero value to this register, the Timeout bit of the ISR register will be set whenever the TCTR reaches that value. The Timeout bit will never be set whilst the TimerInt register is zero. 005Ch-005Fh - - Reserved 0060h-0063h PHYAR RW PHY Access Register 0064h-006Bh - - Reserved 006Ch PHYStatus R PHY Status Register 006Dh~0083h - - Reserved 0084h–008Bh Wakeup0 RW Power Management wakeup frame0 (64bit) 008Ch–0093h Wakeup1 RW Power Management wakeup frame1 (64bit) 0094h–009Bh Wakeup2LD RW Power Management wakeup frame2 (128bit), Low DWord 009Ch–00A3h Wakeup2HD RW Power Management wakeup frame2, High DWord 00A4h–00ABh Wakeup3LD RW Power Management wakeup frame3 (128bit), Low DWord 00ACh–00B3h Wakeup3HD RW Power Management wakeup frame3, High DWord 00B4h–00BBh Wakeup4LD RW Power Management wakeup frame4 (128bit), Low DWord 00BCh–00C3h Wakeup4HD RW Power Management wakeup frame4, High DWord 00C4h-00C5h CRC0 RW 16-bit CRC of wakeup frame 0 00C6h-00C7h CRC1 RW 16-bit CRC of wakeup frame 1 00C8h-00C9h CRC2 RW 16-bit CRC of wakeup frame 2 00CAh-00CBh CRC3 RW 16-bit CRC of wakeup frame 3 00CCh-00CDh CRC4 RW 16-bit CRC of wakeup frame 4 00CEh-00D9h - - Reserved 00DAh-00DBh RMS RW Rx packet Maximum Size 00DCh-00DFh - - Reserved 00E0h-00E1h C+CR RW C+ Command Register 00E2h-00E3h - - Reserved 00E4h-00EBh RDSAR RW Receive Descriptor Start Address Register (256-byte alignment) 00ECh MTPS RW Max Transmit Packet Size Register 00EDh-00FFh - - Reserved |
