VI. Support of 8051 Derivatives

Today a large number of 8051 derivatives is available that grows almost monthly! They all use the same instruction set of the MCS-51 processor core, but are different in peripheral components, to cover a wide range of applications. The difference for the assembly language programmer is mainly the varying set of special function registers and interrupt addresses. It is always good practice to use the same SFR names in a microcontroller application program that the manufacturer of the derivative used has defined. For this special processor definition files are provided. They all are include files with the special function register definitions of a particular 8051 derivative. However, the predefined symbols of ASEM-51 must be switched off prior to including the SFR definitions of another derivative as shown below: 

$NOMOD51
$INCLUDE (80C515.MCU)

This would switch off the predefined symbols of the 8051 and include the register definitions of the 80C515 or 80C535 respectively.
Hence it is easy for the user to adapt ASEM-51 to a brandnew 8051 derivative! All what he has to do is to write a corresponding include file with the SFR definitions derived from the manufacturer's data sheet.
Usually the name of every processor definition file is corresponding to the ROM version of a particular derivative. Of course it also applies to the EPROM, OTP, flash, EEPROM, and ROM-less versions (if any) of that derivative.
By the way, the file 8051.MCU provided contains exactly the predefined symbols of ASEM-51, because its internal symbol table has been generated from it!
To switch ASEM-51 to the reduced instruction set of the Philips P83C75x family of microcontrollers, the $PHILIPS control can be used.
The $WINBOND control enables the extended instruction set of the Winbond W77xxxx and W925xxxx families of microcontrollers with Turbo-51 core.

Currently the following processor definition files are provided with ASEM-51:
