purposes.
Image 6.1 - JTAG connector
Its behaviour depends on jumper PL302 (§9.2, Image 3.3). This jumper can enable the debugging unit
of ARM processor inside GE863-PRO3
If jumper GND-JTAGSEL is closed, normal operation JTAG debugger is
active
If jumper 3V1-JTAGSEL is closed, JTAG Boundary scan is active
If jumper PL302 is closed in 3V1-JTAGSEL position, ARM processor will
not execute any code.
