Table 25. Read accesses through F_DATA

14.8.3 F_SETUP- FIFO setup register (address 0Fh)

A FIFO sample count exceeding the watermark event does not stop the FIFO from accepting new data.

The FIFO update rate is dictated by the selected system acquisition rate (ST bits of CTRL_REG2).

When a byte is read from the FIFO buffer the oldest sample data in the FIFO buffer is returned and also deleted

from the front of the FIFO buffer, while the FIFO sample count is decremented by one. It is assumed that the

host application shall use the I2C BURST read transaction to dump the FIFO.
