/*********************************************************************************
 *
 * DESCRIPTION
 * - This is an extension of standard msmhwio.h to support relative addressing
 *   scheme used in SCALe auto-generated sequences.
 * - The objective of this new addressing scheme is enable the same C function
 *   definition to be applicable to multiple baseances of the same block. 
 * - Such code reuse is not feasible with the standard HWIO macros that use a
 *   absolute addressing scheme.
 * - Compared to the standard HWIO macros, the new macros defined here take an
 *   additional parameter 'baseance offset'.  So are the C functions generated
 *   by SCALe Autoseq from .seq inputs.
 * - As such, macros defined in this file must be used with 'seq_msmhwiobase.h',
 *   'seq_msmhwioreg.h', and the C codes generated from SCALe Autoseq.
 * - Macros defined in this file leverage the lower-level macros from the
 *   standard 'msmhwio.h', and the two sets of macros are compatible.
