Can battery level be measured in psoc without adding external connections?

[GrCa_1363456]

Are there any examples of determining external battery level based on resources available inside a PSoC?

The BLE_Battery_Level example offers a method to charge an external capacitor with VRef then read it back on a different pin into the ADC. That requires an external component on Vref, which is already there, but also an external connection between Vref and a GPIO pin,

Greg,

I had a similar question for the PSoC 4.
