Control Expansion Port (Active On Cyclone Universal
FX
Only)
The Control Expansion Port is intended for future use and is not currently enabled. The location of
the Control Expansion Port is shown in
Figure 3-4
.
3.15
Optional Oscillator (MON08 Only)
The
Cyclone Universal
and
Cyclone Universal
FX
provide a software configurable 9.8304MHz
or 4.9152 MHz oscillator clock signal to Pin 13 of the MON08 Connector. The user may use this
clock signal to overdrive the target RC or crystal circuitry. If this signal is not used, just leave Pin 13
of the target MON08 header unconnected.
Please note that if the target already uses an oscillator as its clock, the Cyclone will NOT be able to
overdrive it. The clock should have sufficient drive to be used with a target system even if the
target system has an RC circuit or crystal connected.
3.16
Cyclone Time / Real Time Clock
The Cyclone is equipped with a Real Time Clock (RTC) module designed to keep accurate timing
even when the Cyclone is turned off.
The Date & Time are displayed on the home screen. Date/Time settings can be configured by
navigating to the following menu using the touchscreen display:
Main Menu / Configure Cyclone Settings / Configure Time Settings
For more information on the available configuration options, see
Section 4.2.3.2 - Configure
Time Settings (Cyclone Time / Real Time Clock)
.
3.17
Power Jumper Settings
The Power Jumpers must be set differently for various power management options that the
Cyclone Universal
and
Cyclone Universal
FX
offer. If the target is being powered independently
of the Cyclone, all pins in the Power Jumpers header must instead be left unpopulated. To reveal
the Power Jumpers header, lift the access panel on the left end of the Cyclone. The location is
indicated as Power Jumpers in
Figure 3-5
. Please see
Section 3.28 - Target Power
Management
for the correct jumper settings for the Cyclone’s power management options. A
quick guide to these settings is also located on the underside label of the Cyclone.
3.18
Debug Connectors
The
Cyclone Universal
and
Cyclone Universal
FX
each provide six shrouded, un-keyed, 0.100-
inch pitch dual row 0.025-inch square headers, and two shrouded, keyed 0.050-inch pitch dual row
mini headers, in order to support target connections to several 8-/16-/32-bit architectures. To
reveal the headers and connect/disconnect ribbon cables, lift the access panel on the left end of
the Cyclone. Each header is designated for one or more specific target architectures, as indicated
in
Figure 3-5
.
