Function

EEI feature can disrupt segment erase

Description

When a flash segment erase operation is active with EEI feature selected (EEI=1 in FLCTL1) and GIE=0, the following can occur:

An interrupt event causes the flash erase to be stopped, and the flash controller expects an RETI to resume the erase. Because GIE=0, interrupts are not serviced and RETI will never happen.

Workaround

1) Do not set bit EEI=1 when GIE = 0.
or,
2) Force an RETI instruction during the erase operation during the check for BUSY=1 (FCLTL3).

Sample code:

        MOV R5, 0(R5) ; Dummy write, erase segment
LOOP: BIT #BUSY, &FCTL3 ; test busy bit
       JMP SUB_RETI ; Force RETI instruction
        JNZ LOOP ; loop while BUSY=1

SUB_RETI: PUSH SR
