ovicin 1:a6f1d535bbdb 9 * IS2 is available for address selection and enables the user to connect up to two MGC3X30 devices on the same bus without address conflict.
ovicin 1:a6f1d535bbdb 10 * The MGC3X30 I2C addresses are 0x42 and 0x43. They are given as device addresses without the R/W bit.
ovicin 1:a6f1d535bbdb 11 * In addition, MGC3X30 requires a dedicated transfer status line (TS), which features a
ovicin 1:a6f1d535bbdb 12 * data transfer status function. The TS is used by both I2C Master and Slave to control
ovicin 1:a6f1d535bbdb 13 * the data flow. I2C SCL, I2C SDA and TS lines require an open-drain connection on
ovicin 1:a6f1d535bbdb 14 * MGC3X30 and the connected host controller. To function properly, I2C SCL and I2C
ovicin 1:a6f1d535bbdb 15 * SDA need to be pulled up to VCC with 1.8 kΩ resistors and the TS line needs to be
ovicin 1:a6f1d535bbdb 16 * pulled up to VCC with a 10 kΩ resistor.
