A.6. JTAG connector signals

Figure A.5 shows the pinout of the JTAG connector and Table 3.6 lists the JTAG and related signals. All JTAG active HIGH input signals have pull-up resistors except DGBRQ which is active LOW and has a pull-down resistor).


The term JTAG equipment refers to any hardware that can drive the JTAG signals to devices in the scan chain. Typically this is RealView ICE or Multi-ICE, although hardware from other suppliers can also be used to debug ARM processors.
