FIFO_STREAM FIFO stream or “continuous” write mode. This bit enables
the FIFO to be used as a moving sample buffer, discarding
the oldest sample data when the FIFO is full and new
sample data arrives. This is intended to work primarily with
SWAKE mode, but CWAKE mode is also supported. Note
that the FIFO_EN bit must be set to ‘1’ for this bit to
function. FIFO stream mode works in I2C mode and both
SPI modes.
0: FIFO steam mode is disabled, FIFO stops accepting new
data when FULL (default)
1: FIFO stream mode is enabled, FIFO discards oldest
samples once new data arrives
6
EXT_TRIG_POL External trigger polarity.
0: Trigger polarity is negative edge triggered (default)
1: Trigger polarity is positive edge triggered
7
EXT_TRIG_EN
External trigger mode enabled.
0: External trigger mode is not enabled (default)
1: External trigger mode is enabled, use INTN pin as the
external trigger input.
This mode is not used with the TRIG_CMD bit in Register
0x10 bit 7. To use this mode, set the TRIG mode in
Register 0x10 bits [2:0].
