The FS_Release_FS0b command calculates and sends the right secure16-bit word to
release FS0b.
A simplified way to release FS0b after power up is to, first, select the right type of
watchdog configured in the OTP, then, hit FS0b Release script button. This sends the
right sequence to close the initialization sequence, sets the error counter back to 0, then
releases FS0b.
