Chip Erase
Chip Erase is not functional on the following devices and executing Chip Erase will cause the device to remain in DAL = 0 mode until the next power cycle or reset:
PIC32CZ4010CA80208, PIC32CZ4010CA80176, PIC32CZ4010CA80144, PIC32CZ4010CA80100, PIC32CZ4010CA91208, PIC32CZ4010CA91176, PIC32CZ4010CA91144, and PIC32CZ4010CA91100.
Warning: To prevent the device from becoming
inaccessible during development, the DAL level must remain at DAL = 2. The DAL
level should only be lowered after development is completed and the device can
be securely locked.
Workaround
In order to achieve a full device erasure, the user must implement an ‘as needed function’ to perform a page-by-page erase and clearing of RAM contents.
