Test Reset — As an input, a low signal on this pin provides a
reset signal to the JTAG TAP controller. To ensure complete
hardware reset, TRST should be asserted whenever RESET is
asserted. The only exception occurs in a debugging environment
when a hardware device reset is required and the JTAG/EOnCE
module must not be reset. In this case, assert RESET, but do not
assert TRST.
To deactivate the internal pull-up resistor, set the JTAG bit in the
SIM_PUDR register.
