INT_SOURCE_REG (64h)

When interrupt latched is selected, reading this register resets all the bits in this register.

Table 34. INT_SOURCE_REG register

Table 35. INT_SOURCE_REG register description

8.10

INT_THS_L_REG (65h)

This register contains the least significant bits of the threshold value chosen for the interrupt.

Table 36. INT_THS_L_REG register

Table 37. INT_THS_L_REG register description

8.11

INT_THS_H_REG (66h)

This register contains the most significant bits of the threshold value chosen for the

interrupt.

Table 38. INT_THS_H_REG register

IEL

Controls whether the INT bit (INT_SOURCE_REG (64h)) is latched or pulsed. Default: 0

If IEL = 0, then INT is pulsed.

If IEL = 1, then INT is latched.

Once latched, INT remains in the same state until INT_SOURCE_REG (64h) is read.

IEN

Interrupt enable. When set, enables the interrupt generation. The INT bit

is in INT_SOURCE_REG (64h). Default: 0

INT

P_TH_S_X

X-axis value exceeds the threshold positive side

P_TH_S_Y

Y-axis value exceeds the threshold positive side

P_TH_S_Z

Z-axis value exceeds the threshold positive side

N_TH_S_X

X-axis value exceeds the threshold negative side

N_TH_S_Y

Y-axis value exceeds the threshold negative side

N_TH_S_Z

Z-axis value exceeds the threshold negative side

MROI

MROI flag generation is alway enabled.This flag is reset by reading

INT_SOURCE_REG (64h).

INT

This bit signals when the interrupt event occurs.
