6.8 FLASH24

FLASH Module

Category

Functional

Function

Write or erase emergency exit can cause failures

Description

When a flash write or erase is abruptly terminated, the following flash accesses by the CPU may be unreliable resulting in erroneous code execution. The abrupt termination can be the result of one the following events:
1) The flash controller clock is configured to be sourced by an external crystal. An oscillator fault occurs thus stopping this clock abruptly.
or
2) The Emergency Exit bit (EMEX in FCTL3) when set forces a write or an erase operation to be terminated before normal completion.
or
3) The Enable Emergency Interrupt Exit bit (EEIEX in FCTL1) when set with GIE=1 can lead to an interrupt causing an emergency exit during a Flash operation.

Workaround

1) Use the internal DCO as the flash controller clock provided from MCLK or SMCLK.
or
2) After setting EMEX = 1, wait for a sufficient amount of time before Flash is accessed again.
or
3) No Workaround. Do not use EEIEX bit.
