SPI modes

The typical value of R is 100 kΩ, assuming that the time constant R*Cp (Cp = parasitic

capacitance of the bus line) is short enough, as the S and C lines must reach the correct

state (S = High and C = Low) while the SPI bus is in high impedance.

Example: Cp = 50 pF, that is R*Cp = 5 µs <=> the application must ensure that the Bus

Master never leaves the SPI bus in the high impedance state for a time period shorter than

5 µs.
