CS42516
6.20.4 D TO E U-BUFFER TRANSFER (DETU)
Default = 0
Function:
Indicates when the user status buffer has changed.
6.20.5 ADC OVERFLOW (OVERFLOW)
Default = 0
Function:
Indicates that there is an over-range condition anywhere in the CS42516 ADC signal path.
6.20.6 RECEIVER ERROR (RERR)
Default = 0
Function:
Indicates that a receiver error has occurred. The register “Receiver Errors (address 26h) (Read Only)”
on page 67 may be read to determine the nature of the error which caused the interrupt.

Function:
The bits of this register serve as a mask for the interrupt sources found in the register “Interrupt Status
(address 20h) (Read Only)” on page 63. 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 Interrupt 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 interrupt pin becomes active during the interrupt condition. Be aware that the active
level(Active High or Low) only depends on the INT(1:0) bits located in the register “Receiver Mode
Control (address 1Eh)” on page 61.
