Functional Description
12.5.1
Test Pin
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 manufac-
turing test.
12.5.2
EmbeddedICE
(Embedded In-circuit Emulator)
The ARM7TDMI EmbeddedICE is supported via the ICE/JTAG port.The internal state of the ARM7TDMI is exam-
ined through an ICE/JTAG port.
The ARM7TDMI processor contains hardware extensions for advanced debugging features:
In halt mode, a store-multiple (STM) can be inserted into the instruction pipeline. This exports the contents of
the ARM7TDMI registers. This data can be serially shifted out without affecting the rest of the system.
In monitor mode, the JTAG interface is used to transfer data between the debugger and a simple monitor
program running on the ARM7TDMI processor.
There are three scan chains inside the ARM7TDMI processor that support testing, debugging, and programming of
the Embedded ICE. The scan chains are controlled by the ICE/JTAG port.
EmbeddedICE mode is selected when JTAGSEL is low. It is not possible to switch directly between ICE and JTAG
operations. A chip reset must be performed after JTAGSEL is changed.
For further details on the EmbeddedICE, see the ARM7TDMI (Rev4) Technical Reference Manual (DDI0210B).
12.5.3
Debug Unit
The Debug Unit provides a two-pin (DXRD and TXRD) USART that can be used for several debug and trace pur-
poses and offers an ideal means for in-situ programming solutions and debug monitor communication. Moreover,
the association with two peripheral data controller channels permits packet handling of these tasks with processor
time reduced to a minimum.
The Debug Unit also manages the interrupt handling of the COMMTX and COMMRX signals that come from the
ICE and that trace the activity of the Debug Communication Channel.The Debug Unit allows blockage of access to
the system through the ICE interface.
A specific register, the Debug Unit Chip ID Register, gives information about the product version and its internal
configuration.
