9.2.1.2 Detailed Design Procedure
The CDCUN1208LP is a easy-to-use device. The user determines the following parameters in order:
In control mode:
- Pin control mode or SPI mode (host interface) : this is done by externally pulling up or pulling down the MODE pin.
In pin control mode:
- The input type, optional input divider ratio and input multiplexer selection should be set.
- The output type, optional output edge rate control, and output enable should be set. This is described in detail in Device Control Using Configuration Pins.
In host control mode:
- SPI interface should be connected to the host (only one CDCUN1208LP device can be connected to the bus).
- Communication should follow the procedure described in Device Control Using the Host Interface.
