Figure 7.2.1 JTAG Interface Signals and Registers
The JTAG boundary-scan mechanism (referred to in this chapter as
JTAG mechanism)
allows testing of the connections between the processor, the printed circuit board to which it is
attached, and the other components on the circuit board.
The JTAG mechanism does not provide any capability for testing the processor itself.
