2.4.3.5
The End Programming command terminates the
program process by removing the high programming
voltage from the memory cells and resetting the data
input latches to all ‘1’s (erased state). A delay of T
(see Table 5-1) is required before the next command to
allow the high programming voltage to discharge (see
Figure 2-7.

2.4.3.6
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 2-8).
