1) We are working on the DP83867IRREG ethernet phy chip ( EVM board) and wanted to set it to 100 Mbps mode. By default switch is using 1000 Mbps.
Package - VQFN - (48Pin)
Does this Switch support 100Mbps speed for RGMII interface.
2) To set the 100mbps we are setting the 6th Bit (Force_100_OK) of the register : 100BASE-TX Configuration Register (100CR), Address 0x0043
But Still 100 Mbps mode is not getting set. ( Auto negotiation is disabled, Full Duplex)
Which register we need to configure to set the 100Mbps Speed?
3) As per the mode selection RX clock will vary depending upon the speed.
But Does GTX clock will also vary as per the speed selected?
Waiting for your reply,
Thanks,
Vipul
