3.1.2.5
The End Programming command terminates the
program process. A delay of T
required before the next command to allow the internal
programming voltage to discharge (see Figure 3-6).

3.1.2.6
After this command is performed, the entire program
memory and Configuration Word is erased.
To perform a Bulk Erase of the program memory and
configuration fuses, the following sequence must be
performed (see Figure 3-12).
