3.8. QSPI Read Opcode

The control block uses 0Bh (1-1-1 fast read) flash opcode to perform read operation during ASx1, and EBh (1-4-4 fast read) flash opcode to perform read operation during ASx4.

Take note of both opcodes’ dummy clock cycle in the respective QSPI flash device datasheet. They must be defined when generating programming file.

Refer to the Generating Programming Files Using the Convert Programming Files Feature section for more information.
