These two fields determines the maximum number of CLK_MCI cycles that the MCI waits between two data block transfers. Its
value is calculated by (CSTOCYC x Multiplier).
These two fields also determine the maximum number of CLK_MCI cycles that the MCI waits between the end of the data
transfer and the assertion of the completion signal. The data transfer comprises data phase and the optional busy phase. If a
non-DATA ATA command is issued, the MCI starts waiting immediately after the end of the response until the completion signal.
If the data time-out defined by CSTOCYC and CSTOMUL has been exceeded, the Completion Signal Time-out Error bit in the
SR register (SR.CSTOE) is set.
Multiplier is defined by CSTOMUL as shown in the following table:
