TABLE 28-4:
28.6.1
The program memory may be read to, or written from,
any location using the table read and table write
instructions. The Device ID may be read with table
reads. The Configuration registers may be read and
written with the table read and table write instructions.
In normal execution mode, the CPx bits have no direct
effect. CPx bits inhibit external reads and writes. A block
of user memory may be protected from table writes if the
WRTx Configuration bit is ‘ 0 ’.
The EBTRx bits control table reads. For a block of user
memory, with the EBTRx bit set to ‘ 0 ’, a table read
instruction that executes from within that block is allowed
to read. A table read instruction that executes from a

Code protection bits may only be written to
a ‘ 0 ’ from a ‘ 1 ’ state. It is not possible to
write a ‘ 1 ’ to a bit in the ‘ 0 ’ state. Code
protection bits are only set to ‘ 1 ’ by a full
chip erase or block erase function. The full
chip erase and block erase functions can
only be initiated via ICSP or an external
programmer.
