Pins 3, 5, 9, 15, 17, and 19 are GND pins connected to GND in I-jet. They should also
be connected to GND in the target system.
Description
JTAG data output from target CPU. Typically connected
to TDO of the target CPU. When using SWD, this pin is
used as Serial Wire Output trace port. (Optional, but not
required for SWD communication.)
This pin (normally pin 7) does not exist.
JTAG data input of target CPU. It is recommended that
this pin is pulled to a defined state on the target board.
Typically connected to TDI of the target CPU. For CPUs
which do not provide TDI (SWD-only devices), this pin is
not used. I-jet will ignore the signal on this pin when using
SWD.
Target CPU reset signal. Typically connected to the
RESET pin of the target CPU, which is typically called
nRST, nRESET, or RESET.
This pin can be used for supplying 5 V power to the
target hardware from I-jet.
Input trace clock.
This pin can be used for supplying 5 V power to the
target hardware from I-jet.
