These two fields determine the maximum number of CLK_MCI cycles that the MCI waits between two data block transfers.
It is equal to (DTOCYC x Multiplier).
If the data time-out defined by DTOCYC and DTOMUL has been exceeded, the Data Time-out Error bit in the SR register
(SR.DTOE) is set.
Multiplier is defined by DTOMUL as shown in the following table
