The TCC parameter defines the duration of constant current phase during gate turn-on and

turn-off sequences (Section 7.16 on page 34).

The TBOOST parameter defines the duration of the overboost phase during gate turn-off

(Section 7.16).

The WD_EN bit enables the clock source monitoring (Section 7.8.2 on page 29).
