1.4.1 Erasing Memory

PFM is erased by row or in bulk, while EEPROM and the Configuration Words can be erased by word or in bulk. ‘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:
  1. Bulk erasing is not supported in self-write operations.
  2. The ICSPDIS Configuration bit cannot be Bulk Erased once the ICSPDIS bit has been set. Refer to the Enhanced Code Protection section for more details.
