4.1.3 Direction and Brake pin override

Direction and Brake pin override will be helpful in applications where it is not intended for the users to affect the direction and brake pins in the device. In such cases, it is recommended to override both pins and configure them via EEPROM.

Direction pin in MCT8316A can be overwritten by configuring DIR_INPUT. Configuring DIR_INPUT to 01b will overwrite Hardware pin to clockwise rotation if motor phases A, B and C are connected to OUTA, OUTB and OUTC respectively. Commutation sequence in clockwise direction will be OUTA-OUTB-OUTC. Configuring DIR_INPUT to 10b will overwrite Hardware pin to anti-clockwise rotation if motor phases A, B and C are connected to OUTA, OUTB and OUTC respectively. Commutation sequence in anti-clockwise direction will be OUTA-OUTC-OUTB.

BRAKE pin in MCT8316A can be overwritten by configuring BRAKE_INPUT. Configuring BRAKE_INPUT to 01b will overwrite Hardware pin to active braking. Configuring BRAKE_INPUT to 10b will overwrite Hardware pin and disable brake functionality.
