The table 3A in the datasheet mentions how to power the VCC_TAP pin. The conditions specified in the table have to always be meet in order for the part to work correctly.  Therefore, there are no combinations a user should use besides what is specified in the table.

The VCC_TAP pin simply acts as voltage supply in the first three conditions.  It is an internally regulated voltage in the fourth condition, where the pin is left floating. This technique keeps the cross points and levels correct for the four combinations of output flavors and voltages.
