STM8 addressing modes
PM0044
46/162
Doc ID 13590 Rev 3
6.6
Short Pointer Indirect Long addressing mode
The pointer address is a byte, the pointer size is a word, thus allowing up to 128 KB
addressing space, and requires 1 byte after the op-code.
Example:
Figure 16.

Action:
A = [shortptr.w] = ((shortptr.w)) = (($40.w)) = ($42E5) =
$11
Steps to determine
Effective Address
PC = 0409
PC = PC + 2 = 40B

Before Completion
Instruction Complete
New PC = PC +1 = 040C
After Completion
