| help |
| The QSPI peripheral uses DMA and cannot write data that is |
| read from the internal flash. A non-zero value here enables |
| a stack buffer into which data is copied to allow the write |
| to proceed. Multiple transfers will be initiated if the |
| data is larger than the configured limit. Must be a |
| multiple of 4. The feature is disabled when set to 0. |
