For PSoC 4, we do not have a Vref Component. So you cannot directly connect any internal voltage as a comparator input. But an internal IDAC is available. This can be routed to LPCOMP via AMUXBUS. For this IDAC has to be connected to a pin with a resistor to ground. (IDAC connected to AMUXBUS, AMUXBUS connected to LPCOMP).

The CapSense block has two IDACs which can be used for
general purposes if CapSense is not being used.(both IDACs are
available in that case) or if CapSense is used without water
tolerance (one IDAC is available).
IDAC is not using UDB, its part of the system resources.
The reference is +/- 1%, the IDAC accuracy is ~ 3 lsbs, so dominant
accuracy set by reference.
Regards, Dana.

Please note that if you use IDAC with an external resistor to generate reference voltage, complete mux bus will be utilized. This will limit your routing possibilities.
