QSPI Behavior while executing XIP and accessing data not mapped to XIP.

[Jeff4BLE]

The QSPI can be used to read/write data via the DMA registers.

The QSPI interface is used with code is running from the XIP memory area.

Assuming the XIP and data areas are not overlapping, I assume switching between these two modes is a seamless operation. In other words, no configuration needed to switch between the two modes. Is this correct?

What happens to the system performance if the code in the XIP space begins a QSPI DMA data transfer and continues to execute from the XIP region? Is this even possible?

Is there any documented restriction of this kind of operation? And if so, where?

Thanks,

Jeff

Thanks. Is there any objection to making this a public case?
