CPU Module

Category

Compiler-Fixed

Function

SP corruption

Description

When the instruction PUSHX.A is executed using the indirect auto-increment mode with the stack pointer (SP) as the source register [PUSHX.A @SP+] the SP is consequently corrupted. Instead of decrementing the value of the SP by four, the value of the SP is replaced with the data pointed to by the SP previous to the PUSHX.A instruction execution.

Workaround

None. Note that compilers will not generate a PUSHX.A instruction that involves the SP.

Refer to the table below for compiler-specific information.
