2.4.2.5
The End Programming command terminates the
program process by removing the high programming
voltage from the memory cells. A delay of T
Table 5-1) is required before the next command to
allow the internal programming voltage to discharge
(see Figure 2-7).

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 2-11).
