 * The symbol is intended to be used to limit the bit field width
 * thusly:
 * <a_register> = (any_expression) & _BITMASK(x), where 0 < x <= 32.
 * If "any_expression" results in a value that is larger than can be
 * contained in 'x' bits, the bits above 'x - 1' are masked off.  When
 * used with the _SBF example above, the example would be written:
 * a_reg = ((_SBF(5,7) | _SBF(12,0xF)) & _BITMASK(16))
 * This ensures that the value written to a_reg is no wider than
 * 16 bits, and makes the code easier to read and understand.
