0(1)

1. This bit must be set to ‘0’ for the correct operation of the device.

0(1)

IEA

IEL

IEN

Table 126. INT_CFG_M register description

XIEN

Enable interrupt generation on X-axis. Default value: 0

0: disable interrupt request; 1: enable interrupt request

YIEN

Enable interrupt generation on Y-axis. Default value: 0

0: disable interrupt request; 1: enable interrupt request

ZIEN

Enable interrupt generation on Z-axis. Default value: 0

0: disable interrupt request; 1: enable interrupt request

IEA

Interrupt active configuration on INT_MAG. Default value: 0

0: low; 1: high

IEL

Latch interrupt request. Default value: 0

0: interrupt request latched; 1: interrupt request not latched)

Once latched, the INT_M pin remains in the same state until INT_SRC_M (31h)) is

read.

IEN

Interrupt enable on the INT_M pin. Default value: 0

0: disable; 1: enable

MROI(1)

1. This functionality can be enabled only if the IEN bit in INT_CFG_M (30h) is enabled.

INT

Table 128. INT_SRC_M register description

PTH_X

Value on X-axis exceeds the threshold on the positive side.

Default value: 0

PTH_Y

Value on Y-axis exceeds the threshold on the positive side.

Default value: 0

PTH_Z

Value on Z-axis exceeds the threshold on the positive side.

Default value: 0

NTH_X

Value on X-axis exceeds the threshold on the negative side.

Default value: 0

NTH_Y

Value on Y-axis exceeds the threshold on the negative side.

Default value: 0

NTH_Z

Value on Z-axis exceeds the threshold on the negative side.

Default value: 0

MROI

Internal measurement range overflow on magnetic value.

Default value: 0

INT

This bit signals when the interrupt event occurs.
