Is there a direct way of measuring the voltage input to the CYBLE-416045 on pin VDD without also routing to an I/O with a voltage divider and measuring with an ADC?

Attched a simple demo project demontrating the internal routing for VBACKUP monitoring.

It just includes a ADC and UART block. The VABCKUP voltage is printed through UART in mV.

I don't see any internal routing for measuring VDD. However, there is internal VBACKUP monitoring. If VDD and VBACKUP connected together in cusotmer's design, I believe the VDD can be measured through VBACKUP.

Can this meet your requirement?

VBACKUP is a separate pin on the module and can likely be tied together with VDD.  What is the procedure for monitoring VBACKUP and getting an accurate voltage reading in PSoC 6?
