Language Extensions

The Compiler contains a language extension for ANSI-C. Use keywords to qualify pointers to distinguish them or to mark interrupt routines.

The Compiler supports the following non-ANSI compliant keywords (see HC(S)08 Backend for semantics).

The topics covered here are as follows:

• Pointer Qualifiers
  
  
• Special Keywords
  
  
• Binary Constants (0b)
  
  
• Hexadecimal Constants ($)
  
  
• The #warning Directive
  
  
• Global Variable Address Modifier (@address)
  
  
• Variable Allocation using @ "SegmentName"
  
  
• Absolute Functions
  
  
• Absolute Variables and Linking
