I don't understand the function of BCTL and BCTLC pins on S12ZVC, I got a description about it is "BCTL is the ballast connection for the on chip voltage regulator. It provides the base current of an external BJT (PNP) of the VDDX and VDDA supplies.", does it for power saving feature when MCU wait mode? does it necessary pin to provide VDDX and VDDA power with on chip voltage regulator?

Thank you,
