bit 7 bit 0
Legend: S = Settable bit HC = Hardware 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 15-11 Unimplemented: Read as ‘0’
bit 10 FRESET: FIFO Reset bit
1 = FIFO will be reset when bit is set, cleared by hardware when FIFO is reset; the user should poll
whether this bit is clear before taking any action
0 = No effect
bit 9 Unimplemented: Read as ‘0’
bit 8 UINC: Increment Tail bit
1 = When this bit is set, the FIFO tail will increment by a single message
0 = FIFO tail will not increment
bit 7-6 Unimplemented: Read as ‘0’
bit 5 TEFTSEN: Transmit Event FIFO Timestamp Enable bit
(1)
1 = Timestamps elements in TEF
0 = Does not timestamp elements in TEF
bit 4 Unimplemented: Read as ‘0’
bit 3 TEFOVIE: Transmit Event FIFO Overflow Interrupt Enable bit
1 = Interrupt is enabled for overflow event
0 = Interrupt is disabled for overflow event
bit 2 TEFFIE: Transmit Event FIFO Full Interrupt Enable bit
1 = Interrupt is enabled for FIFO full
0 = Interrupt is disabled for FIFO full
bit 1 TEFHIE: Transmit Event FIFO Half Full Interrupt Enable bit
1 = Interrupt is enabled for FIFO half full
0 = Interrupt is disabled for FIFO half full
bit 0 TEFNEIE: Transmit Event FIFO Not Empty Interrupt Enable bit
1 = Interrupt is enabled for FIFO not empty
0 = Interrupt is disabled for FIFO not empty
Note 1: These bits can only be modified in Configuration mode (OPMOD<2:0> = 100).
