Scan chains and JTAG interface
Debug scan chains
There are two JTAG-style scan chains within the ARM9E-S. These allow debugging
and EmbeddedICE-RT programming.
The scan chains allow commands to be serially shifted into the ARM core, allowing the
state of the core and the system to be interrogated. The JTAG interface requires only
five pins on the package.
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.
The two scan paths used for debug purposes are referred to as scan chain 1 and scan
chain 2, and are shown in Figure C-1.
