Register Field Mirroring

Recommended Posts

I have a register R with several fields, A and B. R is read-only and volatile as it is a status register. I am finding that a read of R does not seem to update the mirrored values of the fields. Is it supposed too? If not how do I get a single bus read transaction to update all the fields in a register.


R.read(stat, rd_data)




With the above code,

- rval and rd_data match and are as expected.

- aval and bval contain the reset value.

What am I doing wrong here?
