 * Project: Common Include Files
 *
 * Description:
 *     lpc_types.h contains the NXP ABL typedefs for C standard types.
 *     It is intended to be used in ISO C conforming development 
 *     environments and checks for this insofar as it is possible
 *     to do so.
 *
 *     lpc_types.h ensures that the name used to define types correctly
 *     identifies a representation size, and by direct inference the
 *     storage size, in bits. E.g., UNS_32 identifies an unsigned
 *     integer type stored in 32 bits.
 *
 *     It requires that the basic storage unit (char) be stored in 
 *     8 bits.
 *
 *     No assumptions about Endianess are made or implied.
 *
 *     lpc_types.h also contains NXP ABL Global Macros:
 *         _BIT
 *         _SBF
 *         _BITMAP
 *     These #defines are not strictly types, but rather Preprocessor
 *     Macros that have been found to be generally useful.

 * The symbol is intended to be used to limit the bit field width

 * <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.
