Register 0x0C (INT_STATUS_3)
The register contains interrupt status flags. Each flag is associated with a specific interrupt
engine. It is set when the associated interrupt engine triggers. With the exception of orient<3:0>
the setting of latch_int<3:0> controls if the interrupt signal and hence the respective interrupt
flag will be permanently latched, temporarily latched or not latched. The interrupt function
associated with a specific status flag must be enabled.

flat:
device is in ‘1’ flat, or ‘0’ non flat position;
only valid if (0x16) flat_en = ‘1’
orient<2>:
Orientation value of z-axis: ´0´ upward looking, or ´1´ downward
looking. The flag always reflect the current orientation status, independent of
the setting of latch_int<3:0>. The flag is not updated as long as an
orientation blocking condition is active.
orient<1:0>:
orientation value of x-y-plane:
‘00’portrait upright;
‘10’landscape left;
‘01’portrait upside down;
‘11’landscape right;
The flags always reflect the current orientation status, independent of the
setting of latch_int<3:0>. The flag is not updated as long as an orientation
blocking condition is active.
high_sign:
sign of acceleration signal that triggered high-g interrupt was ‘0’positive, ‘1’
negative
high_first_z:
high_first_y:
high_first_x:
high-g interrupt: ‘1’ triggered by, or ‘0’not triggered by z-axis
high-g interrupt: ‘1’ triggered by, or ‘0’not triggered by y-axis
high-g interrupt: ‘1’ triggered by, or ‘0’not triggered by x-axis
