The voltage reference output connects to the reference input of COMPA. The generated voltage reference is nominally at 0.8 V when using the internal 400 kΩ resistor. To generate and connect the reference voltage to COMPA reference input:
It is also possible to generate other voltages by using an external resistor. To generate and connect the reference voltage to COMPA reference input in this case:
The user must ensure that the COMPA reference input only has one driver at all times. To avoid shorting signals together internally, TI provides ROM-based TI-DriverLib functions that ensure a break-before-make switching of the internal muxes.
