ARM DDI 0165B
Scan chains 1 and 2
The scan chain present between DBGSDIN and DBGSDOUT is connected between
DBGTDI and DBGTDO whenever scan chain 3 is selected, or when any unassigned
scan chain number is selected. If there is more than one external scan chain, a
multiplexor must be built externally to apply the desired scan chain output to
DBGSDOUT. The multiplexor can be controlled by decoding DBGSCREG[4:0].
The scan chains allow serial access to the core logic and to the EmbeddedICE hardware
for programming purposes. Each scan chain cell is simple, and comprises a serial
register and a multiplexor. A typical cell is shown in Figure C-4.
