A detailed description of the I
manual”. This may be found at www.nxp.com/documents/user_manual/UM10204.pdf.
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.
2 XTAL1 clocks or 3 s, whichever is less.
