Before programming, the programmer must confirm
that the programming executive is stored in executive
memory. The procedure for this task is illustrated in
Figure
First, ICSP mode is entered. Then, the unique
Application ID Word stored in executive memory is read.
If the programming executive is resident, the correct
Application ID Word is read and programming can
resume as normal. However, if the Application ID Word is
not present, the programming executive must be
programmed to executive code memory using the
method described in
Programming Executive to

The programming voltage applied to MCLR is V
which is essentially V
devices. There is no minimum time requirement for
holding at V
least P18 must elapse before presenting the key
sequence on PGDx.
The key sequence is a specific 32-bit pattern,
‘0100 1101 0100 0011 0100 1000 0101 0000’
(more
hexadecimal format). The device will enter Program/
Verify mode only if the key sequence is valid. The Most
Significant bit (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
Program/Verify mode is to be maintained. An interval
time 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.
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.
Note:
The MCLR pin is briefly driven high then low.
A 32-bit key sequence is clocked into PGDx.
MCLR is then driven high within a specified
period of time and held.

Entering Enhanced ICSP Mode
When programming a device without
Peripheral Pin Select (PPS) and in
Enhanced ICSP mode, the SPI output pin
(SDOx) may toggle while the device is
being programmed.
