  • Patch Set #2, Line 22495: FEATURE_4BA_ENTER_WREN

    Does enter/exit 4-byte mode depend on WREN? Or can it be done without WREN? […]

    Since 256Mb or more requires 4 bytes for addressing, the enter/exit 4-byte address mode operation is required.
    XMC has defined enter/exit 4-byte address mode without WREN (06h) command in the SFDP table of 256Mb+ capacity Datasheet.
    We don't need to add WREN (06h) command before enter/exit 4-byte address mode, but it's OK to add WREN (06h) command or no WREN (06h) command in front of it, it won't affect.
