7.2.2 Quick Auto-Negotiation Function
R-IN32M3-EC supports the quick auto-negotiation function which means completing auto negotiation in less time than
the specific time of IEEE802.3 and link up.
If the PHY is corresponding to the quick auto negotiation, auto negotiation can be complete in a shorter time than normal
by reducing the timer time of the three elements described below among the auto negotiation state machine.
⚫ Break Link Timer
The break link timer is defined as the time from PHY links down to auto-negotiation restarts and it is usually 1250 ms.
⚫ Auto-Negotiation Wait Timer
The auto-negotiation wait timer is defined as the waiting time from auto-negotiation stops to parallel detection starts
and it is usually 850 ms.
