14.13.1.2 Receive FIFO Interrupts - RFIF

The receive FIFO interrupts occur when there is a change in the status of the receive FIFO. There are three interrupt sources:

• Receive FIFO Full Interrupt Flag (RFFIF)
• Receive FIFO Half-Full Interrupt Flag (RFHIF)
• Receive FIFO Not Empty Interrupt Flag (RFNIF)

All three interrupts can be enabled individually. The interrupts cannot be cleared by the application; they will be cleared when the condition of the FIFO terminates.

The three interrupt sources are OR’d together and reflected in the RFIF[30:0] (CxRXIF[31:1]) flags.
