6.2 Signal Summary
connections between the processor, the printed circuit board to which it is attached, and the other components
on the circuit board.
The JTAG interface signals are listed below and shown in Figure 6.2.1.
The JTAG boundary-scan mechanism (referred to in this chapter as JTAG mechanism) allows testing of the
The JTAG mechanism does not provide any capability for testing the processor itself.
