38.11.1.3 Transmit FIFO Interrupts (TFIF)
The transmit FIFO interrupts occur when there is a change in the status of
the transmit FIFO. There are three interrupt sources:
- Transmit FIFO Not Full Interrupt Flag (TFNIF)
- Transmit FIFO Half Empty Interrupt Flag (TFHIF)
- Transmit FIFO Empty Interrupt Flag (TFEIF)
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 C1TXIF[31:1] flags.
