Header file for the Philips 8xC750/751/752 
Copyright (c) 1995-1999 Keil Elektronik GmbH  All rights reserved.

Definition of CPU Type in the main program:

  #define P87C750
  #include <reg75x.h>

  other possible types: 83C750, 87C751, 83C751, 87C752, 83C752 

NOTE:
The Bits IDLE, XSTR and XSTP are named twice in the Philips Data 
Handbook in I2C CONTROL and I2C STATUS SFRs.  Therefore in this Regfile 
they are renamed to _IDLE, _XSTR and _XSTP in the I2CSTA register.
