According to specifications, this field is "Reset to 0 after register
reset is completed", so I'm trusting the chip will behave as advertised!
:) We could implement a safety mechanism to avoid looping in case the
chip misbehaves but I don't think it's worth it. What do you think?
I'll address the other comments in v2.
Thanks for reviewing,
