Host configuration mode affords a greater degree of flexibility. Unlike pin configuration mode, in which the pin settings affect the entire device, host configuration mode enables the user to apply different settings to each input and output port, as depicted in Figure 30. This includes the ability to mix and match output type, edge rate control, and output enable settings. The host interface is enabled or selected by strapping the MODE pin either high (for I2C) or low (for SPI) and resetting the device. Additional device features are accessible only through the host interface as well. For instance, the user can configure the input divider (IDIV) to /8 in host configuration mode only. Additionally, the system can power down the device through device registers.
