Description
IEEE 1149.1 scan data input to the device.
IEEE 1149.1 scan data output from the device.
Used only in Adaptive Clocking mode. I-jet monitors
RTCK to determine when to send the next TCK.
Should be tied to the I/O voltage of the target device.
Used by I-jet to detect if target power is active and to
set the JTAG signal voltage reference for level
translators.

it is routed to the TRACEDATA[2] pin on the MIPI20
connector. For proper booting, this pin should be
pulled-up on the target.

Active LOW open-collector signal that can be driven by
I-jet to reset the device and/or the target board.
I-jet senses this line to determine when a board has
been reset by the user or by watchdog timer.
