28.6 - Enable Enhanced ActiPHY Mode
When bit 28.6 is set to a “1”, the Enhanced ActiPHY power management mode is set in the VSC8211. The reset value for this bit
is determined by the Enhanced ActiPHY bit in the CMODE hardware configuration.
28.5 – FDX Status
Bit 28.5 indicates the actual FDX/HDX operating mode of the PHY.
28.4:3 – Speed Status
Bits 27.4:3 indicate the actual operating speed of the PHY.
28.2 – Reserved
This bit must always be set to “1”.
28.1:0 - Enhanced ActiPHY
This sets the time period the PHY stays in ‘Low Power’ State when Enhanced ActiPHY
‘LP Wake-up State’. Refer to
