Tool/software:

The above image is a part of the schematic, TIDA-010933-DCAC-TOP.SchDoc.
PWM_LS_Si and PWM_HS_Si, are connected to MCU GPIO 57 and 56, respectively.
GPIO 56 and 57 are both output, and software-controlled in uINV_DCAC_update_Duty() function in uinv_dcac.h.
Then, why does logic inverter U35A exist? What does it do exactly?
