Bit Description

7:0

FIFO_LVL[9:2]

FIFO Level.

Indicates the number of bytes in FIFO. The FIFO size

is 512byte, thus FIFO_LVL ranges between 0 (empty)

and 512 (full).

Always read FIFO_STATUS0 first and then FIFO_

STATUS1 to get correct FIFO_LVL and the status

information.

Addr: 0xFE

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.

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.
