Scan chains 0, 1, 2, and 3
TAPSM[3:0], TCK1, and TCK2.The list of scan chain numbers allocated by ARM are
shown in Table B-2 on page B-16. An external scan chain can take any other
number.The serial data stream to be applied to the external scan chain is made present
on SDINBS, the serial data back from the scan chain must be presented to the TAP
controller on the SDOUTBS input. The scan chain present between SDINBS and
SDOUTBS is connected between TDI and TDO whenever scan chain 3 is selected, or
when any of the unassigned scan chain numbers 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 SDOUTBS. The multiplexor can be controlled by decoding
SCREG[3:0].
Table B-2 lists the scan chain number allocation.
These enable serial access to the core logic and to EmbeddedICE Logic for
programming purposes. They are described in detail below.
Scan chain 0 and 1
Purpose
Length
Each scan chain cell is fairly simple and consists of a serial register and a multiplexor
as shown in Figure B-4 on page B-17. The scan cells perform two basic functions:
