Function:
The bits of this register serve as a mask for the Status sources found in the register “Interrupt Status - Ad-
dress 0Dh” on page 35. If a mask bit is set to 1, the error is unmasked, meaning that its occurrence will affect
the INT pin and the status register. If a mask bit is set to 0, the error is masked, meaning that its occurrence
will not affect the INT pin or the status register. The bit positions align with the corresponding bits in the Sta-
tus register.

Function:
The two Interrupt Mode registers form a 2-bit code for each Interrupt Status register function. There are
three ways to set the INT pin active in accordance with the interrupt condition. In the Rising-Edge Active
Mode, the INT pin becomes active on the arrival of the interrupt condition. In the Falling-Edge Active Mode,
the INT pin becomes active on the removal of the interrupt condition. In Level-Active Mode, the INT pin re-
mains active during the interrupt condition.
00 - Rising edge active
01 - Falling edge active
10 - Level active
