This section discusses programming the device
through Enhanced ICSP and the programming
executive. The programming executive resides in
executive memory (separate from code memory) and is
executed when Enhanced ICSP Programming mode is
entered. The programming executive provides the
mechanism for the programmer (host device) to
program and verify the dsPIC33F devices using a
simple command set and communication protocol.
There are several basic functions provided by the
programming executive:
• Read Memory
• Erase Memory
• Program Memory
• Blank Check
The programming executive performs the low-level
tasks required for erasing, programming and verifying
a device. This allows the programmer to program the
device by issuing the appropriate commands and data.
A detailed description for each command is provided in

gramming process. First, it must be determined if the
programming executive is present in executive mem-
ory, and then Enhanced ICSP mode is entered. The
program memory is then erased, and the program
memory and Configuration words are programmed and
verified. Last, the code-protect Configuration bits are
programmed (if required) and Enhanced ICSP mode is
exited.
