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.

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

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
