| SPIM peripherals cannot transmit data directly from flash. Therefore, |
| a buffer in RAM needs to be provided for each instance of SPI driver |
| using SPIM peripheral, so that the driver can copy there a chunk of |
| data from flash and transmit it. |
| The size is specified in bytes. A size of 0 means that this feature |
| should be disabled, and the application must then take care of not |
| supplying buffers located in flash to the driver, otherwise such |
| transfers will fail. |
