Debug and Test Pin Description
Functional Description
Test Pin
Embedded In-circuit Emulator
Table 12-1.
One dedicated pin, TST, is used to define the device operating mode. The user must make sure
that this pin is tied at low level to ensure normal operating conditions. Other values associated
with this pin are reserved for manufacturing test.
The ARM9EJ-S Embedded In-Circuit Emulator-RT is supported via the ICE/JTAG port. It is con-
nected to a host computer via an ICE interface. Debug support is implemented using an
ARM9EJ-S core embedded within the ARM926EJ-S. The internal state of the ARM926EJ-S is
examined through an ICE/JTAG port which allows instructions to be serially inserted into the
pipeline of the core without using the external data bus. Therefore, when in debug state, a store-
multiple (STM) can be inserted into the instruction pipeline. This exports the contents of the
ARM9EJ-S registers. This data can be serially shifted out without affecting the rest of the
system.
