access to ground and 3.0V, 1.8V power supply points.
IMPORTANT
Before you apply power to the EVB, please fully read the following sections on how to
correctly configure the board. However, the boards default configuration should not require
any change in configuration before you power on the EVB.
A Failure in configuration of the board may cause device or EVB damage.

2. EVB Configuration
This section details the configuration of each of the EVB functional blocks.
Throughout this document, all default jumper settings are clearly marked with “(D)” and are
shown in blue text. This should allow a more rapid return to the default state of the EVB if
required. Note that all 3 pin jumpers have the default configuration with a jumper header fitted to
pins 1-2 except JP28.
The main EVB functional blocks are shown below to help with quick location of jumpers etc.
The EVB has been designed to try and make it as easy as possible to use. The PCB has detailed
silkscreen legend and, where possible, have been segmented into functional blocks.

2.3 JTAG/ETB Connector (J18)
Appendix Figure 3
The JTAG/ETB connector (J18) on the edge of the EVB supports the 20–pin debug interface connector.
About ETB (Embedded Trace Buffer)
As process speeds increase it is increasingly difficult to obtain trace information off a chip from
the Embedded Trace Macrocell (ETM). This causes difficulties in maintaining acceptable signal
quality or the signals need to be demultiplexed on to what can become a very large number of
trace port pins.
The solution is to provide a buffer area on-chip where the trace information is stored, and read from the chip latter, at a slower rate.
The ETB stores data produced by the ETM. The buffered data can then be accessed by the debugging tools using a JTAG (IEEE 1149.1) interface, as shown in figure 2-6.
** Important **
When connecting or removing the JTAG/ETB debug interface,
power must be removed from both the EVB and the
JTAG/ETB debug interface.
Figure 2-6 JTAG/ETB Connector

2.4 Reset Switch (S1)
Appendix Figure 3
An active low, push button RESET switch (S1) with a MAXIM MAX823REXK-T device is
provided on the EVB. When the 3.0V voltage regulator drops below a certain threshold level
(2.63V), the MAXIM MAX823REXK-T device will automatically assert the MCU reset line in
order to prevent incorrect operation of the MCU or EVB circuitry. The MAXIM
MAX823REXK-T device also provides a de-bounced input for the active low, push button
RESET switch (S1). As the JTAG hardware debug probe has the ability to assert the MCU reset
line, additional open-drain output buffering scheme is created as shown in Figure 2-7.
Figure 2-7 Reset buffering Scheme
