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 ).
9.1.20 CONFIG
The CONFIG register has the following structure:
The OSC_SEL and EXT_CLK bits set the system clock source:
