XSPI interface
The XSPI memories and QSPI emulator supports single mode data transfer at boot;
additionally, NOR flash memory supports octal mode, NAND flash memory supports
qual mode, and QSPI emulator supports quad mode data transfer.
The figure below shows the LS1028ARDB XSPI connections.

A 2x10-pin connector that connects to an
external QSPI flash emulator (DediProg
EM100Pro) through an ISP-ADP-intel-B
cable adapter. The EM100Pro emulator
uses 1.8 V as the input/output voltage.
