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; ‘01’portrait upside down;
‘10’landscape left; ‘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-g interrupt: ‘1’  triggered by, or ‘0’not triggered by z-axis
high_first_y: high-g interrupt: ‘1’  triggered by, or ‘0’not triggered by y-axis
high_first_x: high-g interrupt: ‘1’  triggered by, or ‘0’not triggered by x-axis
