DESCRIPTION
OFST
D4
COLLISION OFFSET ENABLE
: This bit modifies the backoff algorithm to allow
prioritization of modes.
0: Normal Backoff algorithm
1: Forces Backoff algorithm modification to 0 to 2 min (3+n, 10) slot times for first
three collisions, then follows standard backoff.( For first three collisions station
has higher average backoff delay making a low-priority mode.)

12. TRANSMIT STATUS REGISTER (TSR) 04H
(READ)
Each particular bit of this register is set when the corre-
sponding event occurs on the media during transmission
of a packet. The contents of this register are not specified
until after the first transmission and are cleared upon the
start of the next transmission initiated by the host. A read
of this register is necessary after each transmission.
