25.4.5 Register 20E (14h) - Extended PHY Control Register #3
20E.15 Disable Byte Sync
When enabled, the PHY aligns the 10bit data to the boundary of the COMMA character. This bit is valid only in Serial MAC PHY
operating modes.
20E.14 - Reserved
These bits must always be set to ‘”0”.
20E.13 - Enable LED force
When this bit is set, the LED configuration setting “01” becomes ‘Force off’ and the LED configuration setting “11” becomes
‘Force on’. Refer
20E.12:10 SDOP/SDON Output swing Control
These bits set the output swing amplitude (peak-to-peak voltage) of the SDOP/SDON high speed differential outputs.
