+  * Header file to overcome 8051 compiler differences for specifying\r
+  * special function registers. The following compilers are supported:\r
+  * SDCC, Keil, Raisonance, IAR, Hi-Tech, Tasking, Crossware, Wickenhäuser.\r
+  * Unfortunately not for use with Dunfield.\r
+  *\r
+  * SBIT and SFR define special bit and special function registers at the given\r
+  * address. SFR16 and SFR32 define sfr combinations at adjacent addresses in\r
+  * little-endian format. SFR16E and SFR32E define sfr combinations without\r
+  * prerequisite byte order or adjacency. None of these multi-byte sfr\r
+  * combinations will guarantee the order in which they are accessed when read\r
+  * or written.\r
+  * This file is to be included in every microcontroller specific header file.\r
+  * Example:\r
+  *\r
+  * // my_mcu.h: sfr definitions for my mcu\r
+  * #include <compiler.h>\r
+  *\r
+  * SBIT  (P0_1, 0x80, 1);      // Port 0 pin 1\r
+  *\r
+  * SFR   (P0, 0x80);           // Port 0\r
+  *\r
+  * SFR16 (TMR2, 0xCC);         // Timer 2, lsb at 0xCC, msb at 0xCD\r
+  *\r
+  * SFR16E(TMR0, 0x8C8A);       // Timer 0, lsb at 0x8A, msb at 0x8C\r
+  *\r
+  * SFR32 (MAC0ACC, 0x93);      // SiLabs C8051F120 32 bits MAC0 Accumulator, lsb at 0x93, msb at 0x96\r
+  *\r
+  * SFR32E(SUMR, 0xE5E4E3E2);   // TI MSC1210 SUMR 32 bits Summation register, lsb at 0xE2, msb at 0xE5\r
