CPU Module

Category

Compiler-Fixed

Function

CALL SP instruction does not behave as expected

Description

The intention of the CALL SP instruction is to execute code from the stack, instead it skips the first piece of data (instruction) on the stack. The second piece of data at SP+2 is used as the first executable instruction.

Workaround

Write the op code for a NOP as the first instruction on the stack. Begin the intended subroutine at address SP + 2.

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