Internal Voltages available for LP Comparator in PSoC 4
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).
