Resolver requires an excitation signal and it is sourced by C2000 MCU. There are a couple of choices, either a DAC or a PWM could be used. EPWM8A and DAC-C are the possible sources. An 0 Ohm resistor on R5 will chose DAC as the excitation source whereas a 0 Ohm resistor on R4 will select EPWM8A as the excitation source.
