Name:
Access Type: Read-write
• DTOCYC: Data Timeout Cycle Number
• DTOMUL: Data Timeout Multiplier
These fields determine the maximum number of Master Clock cycles that the MCI waits between two data block transfers.
It equals (DTOCYC x Multiplier).
Multiplier is defined by DTOMUL as shown in the following table:
If the data time-out set by DTOCYC and DTOMUL has been exceeded, the Data Time-out Error flag (DTOE) in the MCI
Status Register (MCI_SR) raises.
