TMS
Test Mode Select (3.3 V Input with
Internal pull-up).
JTAG signal that
controls the state transitions of the TAP
controller. This pin is pulled high by an
internal pull-up when not driven.

TDI
Test Serial Data In (3.3 V Input with
Internal pull-up).
JTAG serial test
instructions and data are shifted in on
this pin. This pin is pulled high by an
internal pull-up when not driven.
36
N12
L11
TDO
Test Serial Data Out (3.3 V Output).
JTAG serial data is output on this pin
on the falling edge of TCK. This pin is
held in high impedance state when
JTAG scan is not enabled.

N13
L10
TCK
Test Clock (5 V Tolerant Input).
Provides the clock to the JTAG test
logic.
38
M12
M12
TRST
Test Reset (3.3 V Input with internal
pull-up).
Asynchronously initializes the
JTAG TAP controller by putting it in the
Test-Logic-Reset state. This pin is
pulled by an internal pull-up when not
driven. This pin should be pulsed low
on power-up, or held low, to ensure that
the device is in the normal functional
mode.

Internal Connection 1 (3.3 V Input
with internal pull-down).
Connect to

RESET
Device Reset (5 V Tolerant Input).
This input (active LOW) puts the device
in its reset state which clears the
device internal counters and registers.
