Table 5-3. Crosspoint Switch Settings and Buttons (continued)
Seting or Button Name Behavior
Override MUXSEL[1:0] Pin Control Enables register control of the device crosspoint. This must be selected to make changes to
the crosspoint configuration.
Pair Select Selects the pair of channels that the Crosspoint Mode is applied to. Pair 0 corresponds to
channels 0-1. Pair 1 corresponds to channels 2-3.
Crosspoint Mode Selects the crosspoint configuration for the selected channels. User can select between
Through , Lane Crossing , and Fanout modes. When the Fanout mode is selected, it is
necessary to select which channel is being broadcasted.
Broadcast Channel Selects which channel is broadcasted while a crosspoint is in Fanout mode. After a selection
is made, it is necessary to click the Broadcast button for changes to apply.
5.4 Low Level Page
The Low Level Page allows for direct access to the device registers. Different groups of registers can easily be
jumped to by selecting a group from the Block Select menu.
Figure 5-10. Low Level Page
Selecting a register will allow the user to read and write data to the register. This can be done by entering
hexadecimal register data into the
Data input box. Register data can also be changed by selecting different
configurations under Register Data . After changing register data, it is important to write the data back to the
register. This needs to be done prior to selecting another register, otherwise the change will not be persistent.
For alterations to the channel registers, it is possible to broadcast a change to all channels by first making
changes to the register data and then using the Broadcast button. This will write the register data to the
corresponding register of each channel.
5.5 EEPROM Page
The EEPROM Page allows for generation and modification of an EEPROM hex file. This file can be loaded onto
an EEPROM device and used with the DS560MB410 while the redriver is in Controller mode.
