Invalid ACCVIFG when DVcc in the range of 2.4 to 2.6V
A Flash Access Violation Interrupt Flag (ACCVIFG) may be triggered by the Voltage Changed During Program Error bit (VPE) when DVcc is in the range of 2.4 to 2.6V. However the VPE does not signify an invalid flash operation has occurred.
If the ACCVIE bit is set and a flash operation is executed in the affected voltage range, an unnecessary interrupt is requested. The bootstrap loader also cannot be used to execute write/erase flash operations in this voltage range, because it exits the flash operation and returns an error on an ACCVIFG event.
