* 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.
* 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
*
