Read Output
Mode
Read the threshold
for the FIFO interrupt
bit/pin.
The MFIO pin is used
as the interrupt and
the
host
should
configure this pin as
an input interrupt
pin. The status bit
DataRdyInt
is
set
when this threshold is
reached.

, Output FIFO Format
Definitions.
The internal FIFO read pointer
increments once the sample size bytes
have been read.
Read Input FIFO
for External
Sensors (e.g.,
systems that
have an
externally
supplied
accelerometer)
Read
the
sensor
sample size.

Read Input FIFO
for External
Sensors
