CONNECTOR DESCRIPTIONS

JTAG
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 STM32F107
memory to be programmed with code and executed step by step by the host software.
For more details please refer to IEEE Standard 1149.1 - 1990 Standard Test Access Port and Boundary
Scan Architecture and STM32F107 datasheets and users manual.
