The TCC parameter defines the duration of constant current phase during gate turn-on and
turn-off sequences (Section 6.15 on page 32).
The TBOOST parameter defines the duration of the overboost phase during gate turn-off
(Section 6.15 on page 32).
The WD_EN bit enables the clock source monitoring (Section 6.8.2 on page 27).
