43.5.5 Delay settings
The following table shows the values for the Delay after Transfer (t
DT
) and CS to SCK
Delay (T
CSC
) that can be generated based on the prescaler values and the scaler values set
in the CTARs. The values calculated assume a 100 MHz system frequency.
NOTE
The clock frequency mentioned above is given as an example in
this chapter. See the clocking chapter for the frequency used to
drive this module in the device.
