TDI
I, PU
Boundary scan test data input.
TDI contains an internal 150 kohm pull-up
resistor.
L8

TMS
I, PU
Boundary scan test mode select input.
TMS contains an internal 150 kohm pull-up
resistor.
L9

TCK
I, PU
Boundary scan test clock input.
TCK contains an internal 150 kohm pull-up
resistor.
M9

TRSTn
I, PU
Boundary scan test reset input. Active low.
TRSTn contains an internal 150 kohm pull-
up resistor as per the 1149.1 specification.
After power up, the JTAG state machine
should be reset by applying a low signal on
this pin, or by keeping TMS high and apply-
ing 5 TCK pulses, or by pulling this pin low
by a 4.7 kohm resistor.
