Description
Active LOW signal that causes all test and debug logic in
the device to be reset along with the IEEE 1149.1 TAP.
machine and logic.
Directs the next state of the IEEE 1149.1 TAP state
machine.
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.
modes and other features. I-jet does not use this pin but
it is routed to the TRACEDATA[3] pin on the MIPI20

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.
