    PWM signal terminals from the USB2ANY are disconnected to such signal terminals of the TPS929120- Q1 device on the TPS929120EVM. As a result, an extra instrument for generating the PWM or clock signal is required to simulate the external PWM or clock input to TPS929120EVM, because both signal outputs from USD2ANY board are not transmitted to TPS929120EVM if TPS929120CANEVM is connected.
