RXFTLR
Receive FIFO Threshold level.
This register controls the threshold value for the receive FIFO memory.
The DW_apb_ssi is enabled and disabled by writing to the SSIENR register.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Receive FIFO Threshold. Controls the level of entries (or above) at which the receive FIFO controller triggers an interrupt. The FIFO depth is configurable in the range 2-256. This register is sized to the number of address bits needed to access the FIFO. If you attempt to set this value greater than the depth of the FIFO, this field is not written and retains its current value. When the number of receive FIFO entries is greater than or equal to this value + 1, the receive FIFO full interrupt is triggered. |
