//
//
// The regs.h include file provides several "generic" macros that can be used
// as an alternate syntax for the various register operations. Because most
// operations involve using two or more of the above defines/macros, the <module>,
// <regname> and <field> are often repeated in a C expression. The generic
// macros provide shorthand to avoid the repetition. Refer to the following
// examples for the alternate syntax.
The C++ style comments above represent a single-instance block. For multiple-instance
blocks, the macros are similar, but have an instance number as the first parameter where
needed. (Differences only shown below.)
39.5 Examples
The following examples show how to code common register operations using the predefined
include files. Each example shows preferred and alternate syntax and also shows constructs
to avoid. Summaries are provided toward the end.
The examples are valid C and will compile without errors. The reader is encouraged to
compile this file and examine the resulting assembly code.

or instance number.
x is the block instance number. If shown, v is the value field for
the macro.
// HW_<module>_<regname>_ADDR(x)
// HW_<module>_<regname>_<SET | CLR | TOG>_ADDR(x)
// - defines for the indicated register address
//
// HW_<module>_<regname>
// - a define for accessing the primary register using the typedef.
// Should be used as an rvalue (i.e., for reading), but avoided as
// an lvalue (i.e., for writing). Will usually generate RMW when
// used as an lvalue.
//
// HW_<module>_<regname>_RD(x)
// HW_<module>_<regname>_WR(x)
// - macros for reading/writing the primary register as a whole
//
// HW_<module>_<regname>_<SET | CLR | TOG>(x)
// - macros for writing the associated set | clear | toggle registers
//
// Macros and defines that relate to the fields of a register are
named:
//
// BW_<module>_<regname>_<field>(x, v)
// - macro for writing a bit field. Usually expands to a CS
operation.
// Not generated for read-only fields.
