6.11 CPU22

CPU Module

Category

Compiler-Fixed

Function

Indirect addressing mode with the Program Counter as the source register may produce unexpected results

Description

When using the indirect addressing mode in an instruction with the Program Counter (PC) as the source operand, the instruction that follows immediately does not get executed.
For example in the code below, the ADD instruction does not get executed.


mov @PC, R7
add #1h, R4

Workaround

Refer to the table below for compiler-specific fix implementation information.
