Q: Microchip dsPIC/PIC24 device does not work in JTAG chain

Answer:

JTAG TDO pin is not electrically fully compatible with other JTAG devices and JTAG daisy chaining may not work properly. If the PIC is the only device in the scan chain, the problem is not visible. If all devices in the boundary scan chain are to work properly, the PIC must be the last device in the chain (TDO is connected to ViaTAP).
