4.6.1
There are two commands that can used for program-
ming code memory when utilizing the Programming
Executive: PROGW and PROGP. The PROGW command
programs and verifies a single 24-bit instruction word
into the specified program memory address. The sec-
ond and faster command, PROGP, allows up to 64 24-bit
instruction words to be programmed and verified into
program memory starting at the specified address. See
Section 6.0 “The Programming Executive”
description for each of these commands.
Figure 4-4
methodology for both of these commands. In both
cases, 5.6K instruction words of the dsPIC33FJ16MC/
GP10X devices are programmed.

PROGRAMMING METHODOLOGY
If a bootloader needs to be programmed,
the bootloader code must not be pro-
grammed into the first page of code mem-
ory. For example, if a bootloader located
at address 0x200 attempts to erase the
first page, it would inadvertently erase
itself. Instead, program the bootloader into
the second page (e.g., 0x400).
