30.4.3.13 Sampling Register (QSPI_SMPR)
The Sampling Register allows configuration of the scheme how the incoming data from an external serial
flash device are sampled in the QuadSPI module. Its fields are relevant in SFM mode only.

Field Description
ICO Instruction Code Options, additional parameters for the IC instruction specified in the IC field.
Meaning of the individual bits vary for each instruction code and vendor, detailed description in
Tabl e 30-53.
Only applicable in SFM mode
IC Write access: Instruction Code of the SFM command to be executed next.
Read access: Instruction Code of the last SFM command successfully written.
Upon writing this byte a new command sequence is started to the external serial flash device, if the
module is in serial flash mode.
Only applicable in SFM mode
