An emulator connected to the JTAG pins consumes additional power and should be disconnected for power measurements or mass production (stand-alone mode).
When debugging (load code from CCS):
Run-Free and then Disconnect from Target to avoid power consumption
When in stand-alone mode (bootload production code):
If JTAG not used, ensure device does not enter test mode by adding strong (4.7k) pull ups to EMU0 & EMU1, and pull-down TRST (10K)
Pull-up on TDO saves power on DVDDIO rail (as much as approximately 500 µA)
Although only used as an output, the TDO pin uses a bidirectional I/O buffer without an internal pull-up. Pull-up externally to avoid floating input oscillation and associated power consumption.
