// Program Description:
//
// **Important Note**: This header file should be included before including
// a device-specific header file such as C8051F300_defs.h.
//
// Macro definitions to accomodate 8051 compiler differences in specifying
// special function registers and other 8051-specific features such as NOP
// generation, and locating variables in memory-specific segments.  The
// compilers are identified by their unique predefined macros. See also:
// http://predef.sourceforge.net/precomp.html
//
// SBIT and SFR define special bit and special function registers at the given
// address. SFR16 and SFR32 define sfr combinations at adjacent addresses in
// little-endian format. SFR16E and SFR32E define sfr combinations without
// prerequisite byte order or adjacency. None of these multi-byte sfr
// combinations will guarantee the order in which they are accessed when read
// or written.
//
// SFR16X and SFR32X for 16 bit and 32 bit xdata registers are not defined
// to avoid portability issues because of compiler endianness.
//
// Example:
// // my_mcu.c: main 'c' file for my mcu
// #include <compiler_defs.h>  // this file
// #include <C8051Fxxx_defs.h> // SFR definitions for specific MCU target
//
// SBIT  (P0_1, 0x80, 1);      // Port 0 pin 1
// SFR   (P0, 0x80);           // Port 0
// SFRX  (CPUCS, 0xE600);      // Cypress FX2 Control and Status register in
//                             // xdata memory at 0xE600
// SFR16 (TMR2, 0xCC);         // Timer 2, lsb at 0xCC, msb at 0xCD
// SFR16E(TMR0, 0x8C8A);       // Timer 0, lsb at 0x8A, msb at 0x8C
// SFR32 (MAC0ACC, 0x93);      // SiLabs C8051F120 32 bits MAC0 Accumulator,
//                             // lsb at 0x93, msb at 0x96
// SFR32E(SUMR, 0xE5E4E3E2);   // TI MSC1210 SUMR 32 bits Summation register,
//                             // lsb at 0xE2, msb at 0xE5
//
// Target:         C8051xxxx
// Tool chain:     Generic
// Command Line:   None
