1 Output numbers are dependent on the value programmed into the MFDR; an MFDR programmed with the maximum frequency (MFDR =
0x20) will result in minimum output timings as shown. The MBUS interface is designed to scale the actual data transition time to move it to
the middle of the SCL low period. The actual position is affected by the prescale and division values programmed into the MFDR; however,
numbers given are the minimum values.

2 Since SCL and SDA are open-collector-type outputs, which the processor can only actively drive low, the time required for SCL or SDA to
reach a high level depends on external signal capacitance and pull-up resistor values.
