Output Test Data Output. This is the serial data output from the shift register. Data is shifted out of the
Input
Test Mode Select. The TMS pin selects the next state in the TAP state machine.
Test Clock. This allows shifting of the data in, on the TMS and TDI pins.
It is a positive edgetriggered clock with the TMS and TCK signals that define the internal state
of the device.
Test Data In. This is the serial data input for the shift register.
device on the negative edge of the TCK signal.
Test Reset. The TRST pin can be used to reset the test logic within the EmbeddedICE logic.

Status green LED with name STAT connected to STM32F103RBT6 pin.53
PC12, note that LED-E SMT jumper should be shorted to may LED work
properly (it’s shorted by default), if you decide to use PC12 port for other
purpose you have to remove the solder short on this jumper which will
disconnect the LED from PC12 port;
Power supply red LED with name PWR – indicates that 3.3V power supply
is applied;
The JTAG connector allows the software debugger to talk via a JTAG (Joint
Test Action Group) port directly to the core. Instructions may be inserted and
executed by the core thus allowing
programmed with code and executed step by step by the host software.
For more details refer to IEEE Standard 1149.1 - 1990 Standard Test Access
Port and Boundary Scan Architecture and
users manual.
