Gate Driver Pins Connecting to MCU Pins (GPIO Connections):
Pins 18-20 (INHC, INHB, INHA): Control output of high-side FETs
Pins 21-23(INLC, INLB, INLA): Control output of low-side FETs
Pin 24 (nFAULT): Fault indicator output
Pin 25 (nSLEEP): When pulled LOW, device will go to low-power sleep mode.
