16.2.8 PAGE_ERASE COMMAND
The PAGE_ERASE command erases the specified
number of pages of code memory from the specified
base address. Depending on the device, the specified
base address must be a multiple of 0x400 or 0x100.
After the erase is performed, all targeted words of code
memory contain 0xFFFFFFFF.
