    How can I detect the voltage of VDD with only internal resources?

      I'm using a CY8CKIT-042 in my design.  ALL my I/O is used for other purposes (LCD, SPI, LEDs and the such).  How can I detect the voltage of VDD with only internal resources?  This is to allow me to set the contract % for the LCD.
