What's the meaning of VTREG , in EVAL-L9963E-MCU evaluation board manual?

[ads85]

In EVAL-L9963E-MCU evaluation board manual,
the term 'VTREG' is refered to on many pages in word.
But schematic diagrams or figures don't use 'VTREG' like the image attached below.
What's the VTREG?

Dear @ads85 ,

VTREG corresponds to VREG in the schematic.

Best Regards
