A DLN adapter generates the DLN_SPI_SLAVE_EVENT_BUFFER_FULL events each time the buffer becomes full.
You can configure the buffer size by calling the DlnSpiSlaveSetEventSize() function. The supported values are from 1 to 256 bytes. By default, the size parameter is set to 256 bytes. To check the current value, use the DlnSpiSlaveGetEventSize() function.
During the transmission from the SPI master, if the buffer is overfilled, a DLN adapter-slave generates the DLN_SPI_SLAVE_EVENT_BUFFER_FULL event.
The eventCount field of the first event is set to zero. For every new DLN_SPI_SLAVE_EVENT_SS_RISE event, the eventCount field increments. When you reset the slave or change its configuration, the eventCount filed is reset to zero.
Use the DlnSpiSlaveEnableEvent() function to enable generating these events. To disable this event, use the DlnSpiSlaveDisableEvent() function. The DlnSpiSlaveIsEventEnabled() function allows to check whether this event is enabled.
The DLN_SPI_SLAVE_EVENT_BUFFER_FULL event does not conflict with other events.
