The HOST_IF_SEL signal is used by the DLPC230-Q1 hardware during system power-up to determine which interface (SPI or I2C) is to be used for host control of the system. The interface that is not selected for host control will be configured as a diagnostic interface which can be used to read diagnostic memory information.
| VALUE AT SYSTEM POWER-UP | SYSTEM ACTION |
|---|---|
| 0 | SPI = Host Control Interface, I2C = Diagnostic Interface |
| 1 | SPI = Diagnostic Interface, I2C = Host Control Interface |
