since the last reading of the register. Status bits that are masked off in the associated mask register
will always be ‘0’ in this register. This register defaults to 00h.
6.13.1 ADC Clock Error (Bit 3)
Function:
Indicates the occurrence of an ADC clock error condition.
6.13.2 DAC Clock Error (Bit 2)
Function:
Indicates the occurrence of a DAC clock error condition.
6.13.3 ADC Overflow (Bit 1)
Function:
Indicates the occurrence of an ADC overflow condition.
6.13.4 ADC Underflow (Bit 0)
Function:
Indicates the occurrence of an ADC underflow condition.

Function:
The bits of this register serve as a mask for the Status sources found in the register “Interrupt Status
- Address 0Dh” on page 46. If a mask bit is set to 1, the error is unmasked, meaning that its occur-
rence will affect the INT pin and the status register. If a mask bit is set to 0, the error is masked, mean-
ing that its occurrence will not affect the INT pin or the status register. The bit positions align with the
corresponding bits in the Status 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 remains active during the interrupt condition.

01 - Falling edge active
