The SelectMAP mode single device option uses an external processor or controller to provide the clock, read/write enable, chip select, and data, as well as monitors the busy signal for flow control to boot and configure a Versal ACAP.

Performance, bank voltage, and MIO usage should be evaluated when selecting the boot mode.
