* Hardware registers access macros.
*
* THE MACROS DEFINED IN THIS FILE ARE DEPRECATED. DO NOT USED FOR NEW
* DEVELOPMENT.
*
* These macros are used to access peripheral's registers. They allow access to
* 8, 16 and 32 bit wide registers. All accesses to peripheral registers should
* be done through these macros in order to ease porting across different
* processors/bus architectures.
*
* Some of these macros also allow to access a specific register field.
