Load Seed
1—Loads the scrambler seed
0—Normal operation
Setting this bit loads the user seed stored
in register 19h into the 100Base-X scram-
bler. The content of this bit returns to 0
after the loading process is completed and
no transmit is active.

User-modifiable seed data. When the
load seed bit (bit 4 of register 18h) is set,
bits 10 through 0 of this register are
loaded into the 100Base-X scrambler.
These 5 bits store the part address used
by the serial management interface.
Upper three of these bits are latched from
the pins during pwerup or hard reset.
Lower two bits are assigned automati-
cally.
