Type

Bit Description

FIFO_OVERFLOW

If set to “1” a FIFO overflow has occurred and data for the

FIFO was lost (e.g. reading from FIFO was too slow). This

flag is cleared by PON and FIFO_CLR. Always check this

flag before and after reading the FIFO. Read

FIFO_STATUS0 and then FIFO_STATUS1 to get consistent

values for both registers.

6FIFO_UNDERFLOW

If set to “1” the FIFO was read out too often and has

returned 0 at least once. In such case the read-out data

may not consistent anymore. This flag is cleared by PON

and FIFO_CLR. Always check this flag before and after

reading the FIFO. Read FIFO_STATUS0 and then

FIFO_STATUS1 to get consistent values for both registers.

5:3

Reserved

2:0

FIFO_LVL[2:0]

See FIFO Status 0 for description. Read FIFO_STATUS0

and then FIFO_STATUS1 to get consistent values for both

registers.

Addr: 0xFE

FIFO_DATA_PROTOCOL

Bit Description

FIFO_DATA_

PROTOCOL

The register FIFO_DATA_PROTOCOL can used to read-out

FIFO data using the protocol mechanism. It can be read

out with single reads or with a block-read.
