memory and perform the following:
1.
2.
Figure 4-2 illustrates this procedure.
If the programming executive is resident, the
Application
programming can resume as normal. However, if the
Application ID Word is not BBh, the programming
executive must be programmed to executive code
memory using the method described in Section 5.4
“Programming the Programming Executive to
Memory”.
Section 3.0 “Device Programming – ICSP” describes
the ICSP programming method. Section 3.13 “Reading
the Application ID Word” describes the procedure for
reading the Application ID Word in ICSP mode.

The programming voltage applied to MCLR is V

requirement for holding at V

the key sequence on PGDx.
The key sequence is a specific 32-bit pattern:
‘0100
0000‘ (more easily remembered as 4D434850h in
hexadecimal
Program/Verify mode only if the key sequence is valid.
The MSB of the most significant nibble must be shifted
in first.
Once the key sequence is complete, V
applied to MCLR and held at that level for as long as
the Program/Verify mode is to be maintained. An
interval of at least P19 and P7 must elapse before
presenting data on PGDx. Signals appearing on PGDx
before P7 has elapsed will not be interpreted as valid.

Program/Verify mode is to be maintained. An interval of
at least P19 and P7 should elapse before presenting
data on PGDx.
Signals appearing on PGDx before P7 has elapsed will
not be interpreted as valid.
On successful entry, the program memory can be
accessed and programmed in serial fashion. While in
the Program/Verify mode, all unused I/Os are placed in
the high-impedance state.
