Setting ”0” at this bit does not count the time as set in
the busreset_detect_time field (bit24:11).

time
0280h
Set the busreset_detect_time. The calculation is
(Setting value) x 125ms.
Annex 1.1.5. MaxArbStateTimeout Register
This register controls the Timeout bit of PHY register. When a PHY is staying in certain state exceeding a time
specified in max_arb_state_time field, the Timeout bit is set. Do not set ”0” for the max_arb_state_time field in
this register.
