• DTOMUL: Data Timeout Multiplier
These fields determine the maximum number of Master Clock cycles that the SMC waits until the detection of a rising edge
on Ready/Busy signal.
Data Timeout Multiplier is defined by DTOMUL as shown in the following table:
If the data timeout set by DTOCYC and DTOMUL has been exceeded, the Data Timeout Error flag (DTOE) in the SMC Sta-
tus Register (SMC_SR) raises.
