Assembler: What means RAM_SP+16H?

I need your help by this assembler code:

LOC  OBJ            LINE     SOURCE
0116               369     controll_time   EQU     RAM_SP+16H      ;enter controll time impulse

What does "RAM_SP+16H" means?

RAM_SP is the storage for C++ data an is equal 0100H.

Solution

  • The expression RAM_SP+16H refers to the address of RAM_SP plus 16 hexadecimal (or 22 decimal). If RAM_SP has address 0100H, this refers to the address 0116H.

    I suppose this is the address of the variable controll_time.
