+  * Header file to overcome 8051 compiler differences for specifying
+  * special function registers. The following compilers are supported:
+  * SDCC, Keil, Raisonance, IAR, Hi-Tech, Tasking, Crossware, Wickenhaeuser.
+  * Unfortunately not for use with Dunfield. 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.
+  * SFR16LEX is provided for 16 bit little endian xdata registers. It is usable
+  * on little endian compilers only; on big endian compilers, these registers
+  * will not be defined.
+  * This file is to be included in every microcontroller specific header file.
+  * Example:
+  *
+  * // my_mcu.h: sfr definitions for my mcu
+  * #include <compiler.h>
+  *
+  * 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
+  *
