The number of clocks from the falling edge of SCL to the first tap (Tap[1]) is defined by the values shown
in the scl2tap column of
tap2tap column in
to determine the delay from the falling edge of SCL to SDA changing, the SDA hold time.
IBC7–6 defines the multiplier factor MUL. The values of MUL are shown in the
