3.4.1
The CDB5560 evaluation board hardware comes pre-configured so the only connection required between
it and a data acquisition system is the serial port connection.
The hardware setup is reconfigurable through the hardware control interface connectors. Configure the
evaluation board by setting the appropriate control line to the appropriate logic level.
3.4.2
The CS5560 ADC communications port features an SPI™ serial port. It can be configured for SSC mode
(Master) or SEC mode (Slave) mode as shown in Table 4. Test points are provided to monitor serial com-
munications.
Connections to the serial interface are made according to the following table.
