From: Ville Syrjälä <[email protected]> I need a scratch register which fill the following requirements: - can be accessed via DSB - all the bits can be read/written - no serious side effects
So far the only thing I could think of is the "expected CRC" register. Add the definition so I can use it. While I only need the hsw+ variant currently, let's define the older variants as well for completeness.
