8.3.2.1 6x PWM Mode

In 6x PWM mode, each half-bridge supports three output states: low, high, or high-impedance (Hi-Z). To

configure DRV8317H in 6x PWM mode, connect the MODE pin to AGND or connect the MODE pin to AGND

via 47-kΩ resistor. To enable 6x PWM mode in DRV8317S, configure the MODE bits with PWM_MODE = 00b or

01b. The corresponding INHx and INLx signals control the output state as listed in Table 8-3.
