Compiler-Fixed

Function

Modifying the PC behaves differently than in previous devices.

Description

When using instructions with immediate or indirect addressing mode to modify the PC, a different value compared to previous devices must be added to get to the same destination.

Example:
  Previous device (MSP430F4619)
label_1 ADD.W #Branch1-label_1-4h,PC

  MSP430F5438:                  
label_1 ADD.W #Branch1-label_1-2h,PC

-----------------------------------------
NOTE: The MOV instruction is not affected
-----------------------------------------

Workaround

1) Add NOP after the PC-modifying instruction
  or
2) Change the offset value in software

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