bit 7 bit 0
Legend: HS = Hardware Settable bit C = Clearable bit
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-4 Unimplemented: Read as ‘0’
bit 3 TEFOVIF: Transmit Event FIFO Overflow Interrupt Flag bit
1 = Overflow event has occurred
0 = No overflow event has occurred
bit 2 TEFFIF: Transmit Event FIFO Full Interrupt Flag bit
(1)
1 = FIFO is full
0 = FIFO is not full
bit 1 TEFHIF: Transmit Event FIFO Half Full Interrupt Flag bit
(1)
1 = FIFO is  half full
0 = FIFO is < half full
bit 0 TEFNEIF: Transmit Event FIFO Not Empty Interrupt Flag bit
(1)
1 = FIFO is not empty
0 = FIFO is empty
Note 1: These bits are read-only and reflect the status of the FIFO.
