2.1.1.2.2 IIM Mode using two separate PWM inputs (Dual PWM Input)

Two separate PWM inputs can be applied to control HI and LI independently. Firstly, remove the Jumper J9 placed on Pin 3 and Pin 4 of J7. Then apply two separate PWM pulses to J6. HI signal is applied to Pin 2 of J6 and LI signal us applied to Pin 3 of J6. Note that the EVM no longer generated dead time separating HI and LI transitions. Therefore, careful consideration must be applied to the control signals in this mode of operation to prevent a shoot-through condition. TI recommends to provide at least 5ns of dead time through the external PWM signals.

Make sure that the short on Pin 3 and Pin 4 of J7 is removed to enable this mode.
