PRODUCTION DATA
The device ccontrol 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 Interface, 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 interface, but not both, to configure the device refer to the Table 6-59.
ADDRA Setting | Mode | Device Address (7-bit) | Device Address (8-bit) |
---|---|---|---|
Short to Ground | I2C | 0x50 | 0xA0 |
Pull down 4.7KOhm to ground | I2C | 0x51 | 0xA2 |
Pull up 22KOhm to AVDD | I2C | 0x52 | 0xA4 |
Pull up 4.7KOhm to AVDD | I2C | 0x53 | 0xA6 |
Short to AVDD | SPI | NA | NA |
