• Long Timeout Action: On a long timeout, either send the device to SLEEP and set a CTL system fault or
send the device to SHUTDOWN.
Power Mode Control
Under this tab, the user can configure the following settings:
• Current Device (xxx): This allows the user to control the power state of the currently selected device through
the device selected drop-down menu. Users can send a selected device to shutdown, sleep, or soft reset.
• Tones to Next Device: This allows the user to control tones that are sent to the next device up the stack.
When in use, users must make sure to change the device selected in the drop-down if they are trying to send
tones to different devices.
• Ping to Bridge Device: This allows the user to control the power state of the current bridge device by
sending pings to it.
Debug
Under this tab, the user can configure the following settings:
• VIF/UART Baud: This allows the user to control the baud rate of the VIf/UART. Additonally, users can see
fault indicators on the COM lines of the base 600 device.
• Debug Control and Comms Status: Users can enable and disable the ability to modify the functionality of
the COM ports. With the debug control enabled, users can turn on and off the COMH and COML ports.
1.2.4 Bridge Control
In this tab, users can control the bridge device and monitor, mask, and reset faults, as well as debug
communications issues on the SPI, UART, and daisy chain interface. At the top of the screen is the
communications mode that is being used for this device. Users must make sure and set this to the correct setting
for their use.
• Control: Here users can enable or disable:
– The sniff detector
– nFault
– Receiver tones
– Heartbeat
– Comm fault detection
– INH
– UART stop bits
These all enable and disable features on the 600 device.
• Fault Control: In this part of the page, users can reset, mask, and unmask faults for the 600 bridge device.
• Fault Status: This contains all of the fault registers, along with the respective bits within them, so that the
user can see which specific faults of each fault register are being set. If a certain element is red, it means that
this bit is active and has been set by the device.
• Diagnostics: Here, users can cause CRC faults on the device in order to test fault detection on 616 devices
further up the stack, as well as on the 600 device itself. Additionally, users can perform power diagnostics
and trigger the INH PMOS pullup.
• SPI Interface: This section can be used to set the SPI clk speed that the USB2ANY propagates to the 600
device.
• Debug: Expanding the debug tab offers an even more detailed breakdown of the faults, allowing the user to
trace back top level faults to specific errors in the communications, power, and so forth.
