Scan chain 0
Scan chain 0 enables access to the entire periphery of the ARM7TDMI core, including
the data bus. The scan chain functions enable inter-device testing (EXTEST) and serial
testing of the core (INTEST). The order of the scan chain, from search data in to out, is:
1.
2.
3.
Scan chain 1
Scan chain 1 is a subset of scan chain 0. It provides serial access to the core data bus
D[31:0] and the BREAKPT signal.
There are 33 bits in this scan chain, the order from serial data in to serial data out, is:
1.
2.
Scan chain 2
Scan chain 2 enables access to the EmbeddedICE Logic registers. Refer to Test data
registers on page B-14 for details.
Data bus bits 0 to 31.
The control signals.
Address bus bits 31 to 0.
A[0] is scanned out first.
Data bus bits 0 to 31.
The BREAKPT bit, the first to be shifted out.
