Hello, Wolfgang
Thank you and I agree with you. It is a little ugly but because these
registers info are not publicly, so I did not use C struct to describe
them, then for this case it it ok or other method such as define a
struct but keep all other registers and bits in this register reserved?
or any method better? Thank you.
Regards
Lei
