Direction and Brake pin override is 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 MCF8315A can be overwritten by configuring [DIR_INPUT]. Configuring [DIR_INPUT] to 01b overwrites 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 is OUTA-OUTB-OUTC. Configuring [DIR_INPUT] to 10b overwrites 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 is OUTA-OUTC-OUTB.

BRAKE pin in MCF8315A can be overwritten by configuring [BRAKE_INPUT]. Configuring [BRAKE_INPUT] to 01b overwrites Hardware pin to low side brake/Align according to [BRAKE_PIN_MODE]. Configuring [BRAKE_INPUT] to 10b overwrites Hardware pin and not low side brake/align.

In Low side braking mode, all the LS FETs are turned ON. In Align braking mode, MCF8315A aligns a motor by injecting dc current through a particular phase pattern.
