5.1.4
Commincation Mode and Rate Settings
Cyclone for ARM devices supports multiple communication modes and
communication rates. A user needs to select proper communication mode
and rate from the drop down list after programming operations are specified.
The debug connector pin definitions are listed for reference.
5.1.5
Target Voltage and Power Settings
A user may elect to use Cyclone for ARM devices to supply power to the
target. In this case, the Target Voltage specifies the target MCU I/O voltage
level.
The user needs to take into account the power discharge time for the Power
Down delay. The reset driver delays, power stabilization time, and the target
clock stabilization time should be considered for the Power Up delay.
A checkbox is available for a user to instruct the Cyclone for ARM devices to
turn off target power after SAP operations. If unchecked, the target power will
remain on.
The user has the option to provide Reset Delay if certain reset monitoring
devices are used. The Cyclone for ARM devices will delay for the specified
time after allowing the target out of reset.
5.1.6
JTAG Daisy Chain
The Cyclone for ARM devices supports processors in a JTAG daisy chain
configuration. This type of configuration is desirable if the user wants to share
a single debug connector across multiple JTAG devices. To use this mode
certain settings must be made in the Cyclone Image Creation Utility. These
are documented in
Section 3.12 - JTAG Daisy Chain
.
5.1.7
Image Description
The Cyclone for ARM devices Configuration Utility allows the user to
summarize the purpose of current configuration for future reference. The
description will be either programmed into the Cyclone for ARM devices or
saved into an encrypted file.
The image description will appear on the LCD screen for image identification.
