QSPI3:SLSO(X) meaning

[samcs]

I read the UM, found every QSPI has a  interface signal, QSPIn_SLSO(X), 

Anybody knows the meaning of X? 

is it SpiCsIdentifier in Davinci CFG pro? 

Thanks

Hi samcs,

Yes, X is the SpiCsIdentifier. Each QSPI module controls 16 hardware channels [0-15] and SpiCsIdentifier specifies the Chip Select (CS) for the hardware specified by SpiHwUnit. It can range from Channel0 (0) to Channel15 (15).

Please refer to the section 37.3.2.2 and "Figure 477 Demultiplexing the Slave Select Signals Externally" in the AURIXTC3XX_um_part2_v2.0 User Manual to understand this.
