DS00002329D-page 77 KSZ9567R 5.1.2.4 I/O Drive Strength Register 5.1.2.5 In-Band Management (IBA) Operation Status 1 Register Address: 0x010D Size: 8 bits Bits Description Type Default 7 RESERVED R/W 0b 6:4 High Speed Drive Strength (24mA) Controls drive strength of RGMII / MII / RMII (except TX_CLK / REFCLKI, COL and CRS) and SYNCLKO. R/W 110b 3 RESERVED R/W 0b 2:0 Low Speed Drive Strength (8mA) Controls drive strength of TX_CLK / REFCLKI, COL, CRS, LEDs, PME_N, INTRP_N, SDO and SDI/SDA/MDIO. R/W 10b Address: 0x0110 - 0x0113 Size: 32 bits Bits Description Type Default 31 Good IBA Packet Detect 1 = A good IBA packet is received. RO 0b 30 IBA Response Packet Transmit Done 1 = An IBA response packet is sent out. This bit is cleared when a packet with a matching IBA tag field is received. RO 0b 29 IBA Execution Done 1 = All the commands in one IBA packet are completely executed. This bit is cleared when a packet with a matching IBA tag field is received. RO 0b 28:15 RESERVED RO 0x0000 14 IBA MAC Address Mismatch Error This bit is active only when IBA_ENABLE (In-Band Management (IBA) Control Register, bit 30) is set. 1 = An IBA packet is received with an unmatched MAC address, unequal to the switch’s MAC address. This bit is cleared when a packet with a matching IBA tag field is received. RO 0b 13 IBA Access Format Error 1 = An IBA packet with a wrong access format (not equal to 0x9800) is received. This bit is cleared when a packet with a matching IBA tag field is received. RO 0b 12 IBA Access Code Error 1 = An IBA packet with an unrecognized access code is received. (Valid access codes are 0x0001 and 0x0002.) This bit is cleared when a packet with a matching IBA tag field is received. RO 0b |
