bit 7

bit 0

Legend:

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 31-29

Unimplemented: Read as ‘0’

bit 28-24

FSIZE<4:0>: FIFO Size bits( 1)

0_0000 = FIFO is 1 Message deep

0_0001 = FIFO is 2 Messages deep

0_0010 = FIFO is 3 Messages deep

...

1_1111 = FIFO is 32 Messages deep

bit 23-11

Unimplemented: Read as ‘0’

bit 10

FRESET: FIFO Reset bit

1 = FIFO will be reset when bit is set, cleared by hardware when FIFO was reset. The user should

wait for this bit to clear before taking any action.

0 = No effect

bit 9

Unimplemented: Read as ‘0’

bit 8

UINC: Increment Tail bit

When this bit is set, the FIFO tail will increment by a single message.

bit 7-6

Unimplemented: Read as ‘0’

bit 5

TEFTSEN: Transmit Event FIFO Time Stamp Enable bit( 1)

1 = Time Stamp objects in TEF

0 = Don’t Time Stamp objects in TEF

bit 4

Unimplemented: Read as ‘0’

bit 3

TEFOVIE: Transmit Event FIFO Overflow Interrupt Enable bit

1 = Interrupt enabled for overflow event

0 = Interrupt disabled for overflow event

bit 2

TEFFIE: Transmit Event FIFO Full Interrupt Enable bit

1 = Interrupt enabled for FIFO full

0 = Interrupt disabled for FIFO full

Note 1:

These bits can only be modified in Configuration mode.
