JTAG Interface
23.2 JTAG Interface Signals
JTAG interface signals are as follows (see Fig. 23-2):
The JTAG boundary scan mechanism (hereafter called "JTAG mechanism") enables testing of the processor,
printed circuit boards connected to the processor, and connections between other components on printed circuit
boards.
The JTAG mechanism does not have a function of testing the processor itself.
