Problem: Typically, we need to change register fields, which occupies some bits of a register. In order to not modify other fields, we must read the whole register first an change only the bits corresponding to that field. This is the regular way way doing this. The issue is that it is easy to use the smio_thsafe_client_() of functions and change the whole register.

Solution: Use the rw_param macros like SET_PARAM and GET_PARAM to read/write only specifc register fields.
