The unit T
MCLK
is the period of the input master clock; The frequency of MCLK is assumed 13.5 MHz
8
The capacitive load is 200 pF
9
A pull-up resistor to VDD is required on each of the SCLK and SDATA lines; for a maximum bus capacitive load of 200 pf, the minimum
value of Rp should be selected in order to meet specifications
