The delay of the data clock is calculated as follows: t

resistor R
(see Figure 24, Figure 25 and Figure 32). When the level of Data_In is equal to the level
of Data_Out, the data clock is issued after an additional delay t
Note that the capacitive load at Pin DATA is limited. If the maximum tolerated capacitive
load at Pin DATA is exceeded, the data clock disappears (see chapter ’Data Interface’).
