PRODUCTION DATA
The device control registers can be accessed using either I2C or SPI communication to the device.
By monitoring the SDA_PICO, SCL_SCLK, GPO1A (or GPIO1)_POCI, and ADDRA_CSZ device pins, which are the multiplexed pins for the I2C or SPI, the device automatically detects whether the host device is using I2C or SPI communication to configure the device. For a given end application, the host device must always use either the I2C or SPI, but not both. To configure the device refer to the Table 6-68.
| ADDRA pin | Mode | Device Address (7-bit) | Device Address (8-bit) |
|---|---|---|---|
| Short to Ground | I2C | 0x50 | 0xA0 |
| Short to AVDD | I2C | 0x51 | 0xA2 |
| CSZ input | SPI | NA | NA |
