A detailed description of the I
may be ordered using the code 9398 393 40011.
Minimum SCL clock frequency is limited by the bus time-out feature, which resets the serial bus interface if SDA is held LOW for a
minimum of 25 ms.
Only applicable to the SC16IS750 and SC16IS760.
2 X1 clocks or 3 s, whichever is less.
