1.4.1 Erasing Memory
Program Flash Memory (PFM) is erased by row or in bulk, where ‘row’ refers to the minimum number
of words that can be programmed/erased and ‘bulk’ includes many subsets of the total
memory space. The duration of the erase is always determined internally and is
determined by the size of the memory. All Bulk ICSP Erase commands have minimum
VDD requirements, which are higher than the Row Erase and Write
requirements.
Important: Bulk
erasing is not supported in self-write operations.
