    enum with assignments is standard?

    just an example:
    Code:
    typedef enum {
    	TimeOut = 0x0938,
    	CC = 0x0A00
    	
    } Type_RegisterAddress;
    the previous use of enum with assignment is ANSI C or it is something working only for some C compilers?

    It's valid in C99; I don't remember whether it was valid in C89.

    Yes you can do that.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Yes, that is ANSI standard C89.
    An enumeration type declares a set of named constants, with type int. An enumerator with = defines enumeration constant. If the first enumerator has no =, its enumeration constant is 0. Each enumerator with no = defines an enumeration constant, by adding 1 to the previous one.
