56F8323 Technical Data
Preliminary

Output
Tri-stated
Test Data Output
— This tri-stateable output pin provides a
serial output data stream from the JTAG/EOnCE port. It is
driven in the shift-IR and shift-DR controller states, and
changes on the falling edge of TCK.

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 EOnCE/JTAG 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.
