6.5 Programming

The device communicates with the system controller through a serial interface, which supports either an I2C-compatible two-wire bus, or an SPI-compatible bus. The device includes a robust mechanism that detects between an SPI-compatible or I2C-compatible controller, and automatically configures the interface accordingly. The interface detection mechanism operates at start-up, thus preventing protocol change during normal operation.

The register map addresses range from 0x00 to 0x32, enabling access of bits within each respective register (see Section 7 for additional details).
