Flash Memory Array and Control
While MCR[DONE] is low, MCR[EHV] is high, and MCR[PSUS] is low, the user may clear MCR[EHV],
resulting in a program abort. A program abort forces the module to step 8 of the program sequence. An
aborted program results in MCR[PEG] being set low, indicating a failed operation. The data space being
operated on before the abort will contain indeterminate data. The user may not abort a program sequence
while in program suspend.
CAUTION
Aborting a program operation leaves the flash core addresses being
programmed in an indeterminate data state. This may be recovered by
executing an erase on the affected blocks.
