The MIO pin options for the boot modes are listed in the MIO Boot Interfaces table. All MIO pin signal options are listed in the MIO-at-a-Glance Tables section.
Interface Connection Diagram
The QSPI flash interface connections are shown in the QSPI Flash Interface Diagrams section.
In QSPI24/QSPI32 boot modes, the BootROM configures MIO pins [0:5] for the single device/dual-stacked flash interface and MIO pins [0:5, 7:12] for the dual-parallel flash interface.
Interface Signals
The QSPI interface signals are listed in the QSPI Flash Interface Signals section of the OSPI flash memory controller chapter.
Note: The loopback clocks signal (LPBK) is not
configured by the BootROM. The PLM firmware can enable the LPBK for higher
frequency.
