Description
JTAG Test Clock. This signal has an internal
weak pull-up resistor.
JTAG Test Data Input. This signal has an
internal weak pull-up resistor.
JTAG Test Data Output
JTAG Test Mode Select. This signal has an
internal weak pull-up resistor.
JTAG Test Reset. This signal has an internal
weak pull-up resistor.
For normal JTAG operation, this signal
should be active at power-up.
If the JTAG interface is not being used, this
signal can be tied low.
