Function

An unexpected Vacant Memory Access Flag (VMAIFG) can be triggered due to the CPU autoincrement of the MAB+2 outside the range of a valid memory block.

Description

The VMAIFG can be triggered under the following conditions:

1. If an interrupt is requested, fetched by the CPU, but lost before excution of the interrupt service routine.

OR

2. If a PC-modifying instruction (e.g. - ret, push, call, pop, jmp, br) is fetched from the last address of a section of memory (e.g.- FLASH, RAM) that is not continguous to a higher, valid section on the memory map.

Workaround

For case 1 - None.
For case 2 - If code is affected, edit the linker command file to make the last four bytes of affected memory sections unavailable.

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