• CSTOCYC: Completion Signal Timeout Cycle Number
These fields determine the maximum number of Master Clock cycles that the HSMCI waits between two data block trans-
fers. Its value is calculated by (CSTOCYC x Multiplier).
• CSTOMUL: Completion Signal Timeout Multiplier
These fields determine the maximum number of Master Clock cycles that the HSMCI waits between two data block trans-
fers. Its value is calculated by (CSTOCYC x Multiplier).
These fields determine the maximum number of Master Clock cycles that the HSMCI 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 HSMCI starts waiting immediately after the end of the response until the comple-
tion signal.
Multiplier is defined by CSTOMUL as shown in the following table:
If the data time-out set by CSTOCYC and CSTOMUL has been exceeded, the Completion Signal Time-out Error flag
(CSTOE) in the HSMCI Status Register (HSMCI_SR) raises.
