Part Number:DP83640
Hi
Currently, we are using the DP83640 PHYTER to link 2 of our equipments. Until this day we linked them at 100M in FullDuplex with auto-negociation. Our customer is asking us to speed up the boot. So now, we are trying to link our PHYTERs in forced mode to avoid extra timing due to auto-negociation.
But we are not able to link PHYTERs by this way. If the BMCR register is loaded with AUTONEG bit set to 0 and with link information (100M/FD), the link status in BSMR register is never set to 1 (as in the PHYSTS register too).
Please let us know suggestions to implement this solution.
