TRST
Input
Test Reset (TRST)
—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, since the Enhanced
OnCE/JTAG module is under the control of the debugger. In this case it is
not necessary to assert TRST when asserting RESET. Outside of a
debugging environment RESET should be permanently asserted by
grounding the signal, thus disabling the Enhanced OnCE/JTAG module
on the device.
Note:
be used in a debugging environment, TRST may be tied to V
SS
through a 1K
resistor.
For normal operation, connect TRST directly to V
SS
. If the design is to

Debug Event (DE)
—This is an open-drain, bidirectional, active low
signal. As an input, it is a means of entering debug mode of operation
from an external command controller. As an output, it is a means of
acknowledging that the chip has entered debug mode.
This pin is connected internally to a weak pull-up resistor.
