⚫ Link Fail Inhibit Timer
The link fail inhibit timer is defined as the waiting time from signal loss or becomes abnormal to link down and it is
usually 850 ms.
These three timers can be set by setting bits 8 to 5 in register 18 (PHY_MODE[3:0] bits). When PHY_MODE[3] is 0,
the value of PHY_MODE[1:0] cannot be reflected. Set PHY_MODE[3] to 1 when using this function.
