9.3 Debug Port Pin Descriptions
The debug port pins default after POR to their JTAG functionality with the exception of
JTAG_TRST_b and can be later reassigned to their alternate functionalities. In cJTAG
and SWD modes JTAG_TDI and JTAG_TRST_b can be configured to alternate GPIO
functions.
9.4 System TAP connection
The system JTAG controller is connected in parallel to the ARM TAP controller. The
system JTAG controller IR codes overlay the ARM JTAG controller IR codes without
conflict. Refer to the IR codes table for a list of the available IR codes. The output of the
TAPs (TDO) are muxed based on the IR code which is selected. This design is fully
JTAG compliant and appears to the JTAG chain as a single TAP. At power on reset,
ARM's IDCODE (IR=4'b1110) is selected.
