11 / 68 page DM9008 ISA/Plug & Play Super Ethernet Contoller Final 11 Version :DM9008-DS-F02 June 14, 2000 Configuration Register B (CRB) Configuration Register B can be read at address 0BH in Page 0 of ENC, and can be written by following a read to address 0BH with a write to address 0BH. If a write to address 0BH is performed without a previous read to 0BH, it will be regarded as a write to register RBCR1 of ENC. 765 432 1 0 -- -- BUSERR CHRDY -- GDLINK PHYS1 PHYS0 Bit Symbol Description 0, 1 PHYS0 PHYS1 Physical Media Interfaces: These two bits determine which type of physical interface the DM9008 is using, as shown below: bit1 bit0 Interface 0 0 Set to 10BASE-T; BNCEN = low 0 1 Set to 10BASE2; BNCEN = high 1 0 Set to 10BASE5; BNCEN = low 1 1 Auto-detection media 2 GDLINK Read: Link status. One indicates Link OK; zero indicates Link Fail 3 -- Reserved 4 CHRDY IOCHRDY from IOR or IOW or from BALE: When low, DM9008 will pull IOCHRDY low after the command strobe. If high, IOCHRDY will be pulled low after BALE goes high 5 BUSERR Bus Error: This bit shows that DM9008 has detected an ISA bus error. This bit will be high if DM9008 inserts wait states into a system access and the system terminates the cycle without inserting wait states 6 -- Reserved 7 -- Reserved |
