nal voltage source.
Serial-Data Output. When I2C/SPI is high, DOUT/SDA functions as the DOUT SPI
serial-data output. When I2C/SPI is low, DOUT/SDA functions as the SDA I
data input/output.
Serial-Clock Input. When I2C/SPI is high, SCLK/SCL functions as the SCLK SPI
serial-clock input (up to 26MHz). When I2C/SPI is low, SCLK/SCL functions as the
SCL I
Active-Low Chip-Select and Address 0 Input. When I2C/SPI is high, CS/A0 functions
as the CS SPI active-low chip select. When I2C/SPI is low, CS/A0 functions as the
A0 I
