The OSC_SEL and EXT_CLK bits set the system clock source:
Oscillator management
The SW_MODE bit sets the external switch to act as HardStop interrupt or not:
Table 26.
The OC_SD bit sets if an overcurrent event causes or not the bridges to turn off; the OCD
flag in the STATUS register is forced low anyway:
