GATECFG2
The GATECFG2 register has the following structure:
The TCC parameter defines the deadtime duration between the gate turn-off and the
opposite gate turn-on sequences (Section 6.16).
The TBLANK parameter defines the duration of the blanking of the current sensing
comparators (stall detection and overcurrent) after each commutation (Section 6.16).
