Please refer to Section 5.4.1 for more information that applies to QSPI boot mode
The QSPI boot mode supports the 1S-1S-4S mode only. The ROM will issue a Fast Read Quad Output command (0x6B) followed by a 24 bit (3 byte) address (the starting address is all zeros), followed by 8 dummy cycles. The flash device should then respond with 4-bit data. The frequency of operation during the quad read portion is 50 MHz.
