Scan chains and JTAG interface
Scan chain implementation
There are three JTAG-style scan chains within the ARM7TDMI core. These enable
debugging and configuration of EmbeddedICE Logic.
A JTAG style Test Access Port (TAP) controller controls the scan chains. For further
details of the JTAG specification, refer to IEEE Standard 1149.1 - 1990 Standard Test
Access Port and Boundary-Scan Architecture.
In addition, support is provided for an optional fourth scan chain. This is intended to be
used for an external boundary-scan chain around the pads of a packaged device. The
control signals provided for this scan chain are described in Scan chain 3 on page B-20.
The scan cells are not fully JTAG compliant.
The following sections describe:
•

The three scan paths are referred to as:

The scan chains are shown in Figure B-1 on page B-4.
