Limits to the current and to the interface speed must be taken into consid-
eration when using the expansion interface. The maximum current limit is
dependent on the capabilities of the used regulator. Additional circuitry
can also add extra loading to signals, decreasing their maximum effective
speed.

JTAG Emulation Port
The JTAG emulation port allows an emulator to access the internal and
external memory of the processor through a 6-pin interface. The JTAG
emulation port of the processor also connects to the USB debugging inter-
face. When an emulator connects to the board at
