8.3.2.3 Asynchronous Modulation
The DIR pin controls the direction of BLDC motor in either clockwise or counter-clockwise direction. Tie the DIR
pin low if this feature is not required.
The BRAKE input halts the motor by turning off all high-side MOSFETs and turning on all low-side MOSFETs
when it is pulled high. This brake is independent of the states of the other input pins. Tie the BRAKE pin low if
this feature is not required.
Table 8-3 shows the configuration in 1x PWM mode with asynchronous modulation.
