6.7.9.1 SVR/LVR Control Configuration Structure
This section describes the PHY auto configuration structure used to configure SVR/LVR control related
circuitry. The programming in this section is applied after power-up.
The SVR/LVR control Configuration Pointer (Global MNG Offset 0x10) points to the start (offset 0x0) of
this type of structure, to configure SVR/LVR Control registers. If pointer is 0xFFFF then no structure
exists.
6.7.9.1.1 SVR/LVR Control Configuration Section Length - Offset 0x0
The section length word contains the length of the section in words. Note that section length count does
not include the section length word and Block CRC8 word.

15:0 Pointer
Pointer to SVR/LVR control configuration structure. Refer to
Section 6.7.9.1 for details of the structure. A value of 0xFFFF means
the pointer is invalid.
