dsPIC33F/PIC24H PROGRAMMING SPECIFICATION
3.2
Confirming the Presence of the
Programming Executive
Before programming, the programmer must confirm
that the programming executive is stored in executive
memory. The procedure for this task is illustrated in
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 Section 6.0 “Programming the
for the Application ID of each device.
the ICSP programming method. Section 5.11 “Reading
the Application ID Word” describes the procedure for
reading the Application ID Word in ICSP mode.

Entering Enhanced ICSP Mode
As illustrated in Figure 3-3, entering Enhanced ICSP
Program/Verify mode requires three steps:
1.
The MCLR pin is briefly driven high then low.
2.
A 32-bit key sequence is clocked into PGDx.
3.
MCLR is then driven high within a specified
period of time and held.
The programming voltage applied to MCLR is VIH,
which is essentially VDD in case of dsPIC33F/PIC24H
devices. There is no minimum time requirement for
holding at VIH. After VIH is removed, an interval of at
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
easily
remembered
as
0x4D434850
in
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, VIH must be
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:
When programming a device without

Enhanced ICSP mode, the SPI output pin
(SDOx) may toggle while the device is
