Scan chain 2
In halt mode debug a request on one of the external debug interface signals, or on an
internal functional unit known as the EmbeddedICE-RT logic, forces the ARM9E-S into
debug state. The events that activate debug are:
•
•
•
•
The internal state of the ARM9E-S is examined using the JTAG serial interface, that
allows instructions to be serially inserted into the core pipeline without using the
external data bus. So, for example, when in debug state, a store multiple (
inserted into the instruction pipeline, and this exports the contents of the ARM9E-S
registers. This data can be serially shifted out without affecting the rest of the system.
a breakpoint (a given instruction fetch)
a watchpoint (a data access)
an external debug request
scanned debug request (a debug request scanned into the EmbeddedICE-RT delay
control register).
