Notes
1. The power-on reset circuit resets the I2C-bus logic with VDD < VPOR and sets all I/Os to logic 1 (with current source
to VDD).
2. The value is not tested, but verified on sampling basis.
3. A single LOW-level output current (IOL) must not exceed 20 mA for an extended time. The sum of all IOLs at any point
in time must not exceed 100 mA.
