0
R_PUSH1
Object detection interrupt for App0; asserted when a
result from object detection is available
int1 status. If bis is asserted, and int1_enab is asserted
as well, then the INT pin will be pulled low. Writing a '1'
here will clear int1 condition.
Note: An interrupt is raised on every result from object
detection including no-target.

RW
Raw histogram available interrupt for App0; asserted
when a raw histogram can be retrieved from I²C.
0=disabled, 1=enabled -> INT output is active if int2
flag is "1"

int1_enab
0
RW
Object detection interrupt for App0; asserted when a
result from object detection is available
0=disabled, 1=enabled -> INT output is active if int1
