Good question!

When Microchip released the dsPIC33, it was supposed to have JTAG
programming. I thought that that was a great plus, because the project I
was developing used a CPLD and it would be great to use a single
connector to program all the devices in the board. BUT the first
documentation (errata) released by Microchip stated that the JTAG was
not operational in the first devices and would be fixed in the future.

We are already in the future now, and I never heard from Microchip of
JTAG programming.

I think that for the PIC32 it is a different matter because their core
is MIPS, which perhaps knows how to do a JTAG interface correctly.
