LS1043A RCW clarification

[mike_palmer]

Looking at the LS1043A Reference Manual (rev 4, 6/2018), RCW source-encodings (Table 4-9), the QSPI (0_0100_010x) and SD/MMC (0_0100_0000) cfg_rcw_src values are footnoted with "Not valid as an RCW[IFC_MODE] encoding."

Can someone clarify what it meant by this footnote?

The mentioned note means that IFC is implicitly initialized in accordance with the RCW source-encoding (the RCW[IFC_MODE] is not used) in all cases except QSPI and SD/MMC when IFC is initialized by the RCW[IFC_MODE].
