1.4.1 Bulk Erase Not Available with LVP
A bulk erase of the Program Flash Memory or Data Memory cannot be executed in Low-Voltage Programming mode.
Work around
Method 1:
If ICSP Low-Voltage Programming mode is required, use row erases to erase the program memory, as described in the “Program/Verify Mode” section of the Programming Specification. Data Memory must be over-written with the desired values.
Method 2:
Use ICSP High-Voltage Programming mode if a bulk erase is required.
Note: Only the bulk erase feature will erase Program or Data
Memory if code or data protection is enabled. Method 2 must be used if code or
data protection is enabled.
