35/54

The contents of the INT1_CFG_REG_A register are loaded at boot.

A write operation at this address is possible only after system boot.

The difference between AOI-6D = ‘01’ and AOI-6D = ‘11’ is defined as follows:

AOI-6D = ‘01’ is movement recognition. An interrupt is generated when the orientation

moves from an unknown zone to a known zone. The interrupt signal stays for a duration

determined by ODR.

AOI-6D = ‘11’ is direction recognition. An interrupt is generated when the orientation is

inside a known zone. The interrupt signal stays until orientation is inside the zone.

INT1_SRC_A (31h)

XHIE/

XUPE

Enable interrupt generation on X high event or on direction recognition. Default value: 0

(0: disable interrupt request; 1: enable interrupt request.)

XLIE/XDO

WNE

Enable interrupt generation on X low event or on direction recognition. Default value: 0

(0: disable interrupt request; 1: enable interrupt request.)

INT1_SRC_A register

0(1)

This bit has to be set to ‘0’ for correct operation.

Table 46.

INT1_SRC_A description

Interrupt active. Default value: 0

(0: no interrupt has been generated; 1: one or more interrupts have been generated)

Z high. Default value: 0

(0: no interrupt, 1: Z high event has occurred)

Z low. Default value: 0

(0: no interrupt; 1: Z low event has occurred)

Y high. Default value: 0

(0: no interrupt, 1: Y high event has occurred)

Y low. Default value: 0

(0: no interrupt, 1: Y low event has occurred)
