Notes:
1. Note that the V_OH specification does not apply to the open-drain SDA/SDIO output when the serial interface is in I²C
mode or is unused with I2C_SEL pulled high. VOL remains valid in all cases.
2. VDDIO is determined by the IO_VDD_SEL bit. It is selectable as V_DDA or V_DD. See the Si5345/44/42 Family Reference
Manual for more details on the proper register settings.
