9.20.8 Mask for Amplifier Error (AmpErrM)
9.21
All bits in this register are considered “level-triggered” events, meaning as long as a condition continues, the corre-
sponding bit will remain set. These status bits are not affected by the interrupt mask bit and the condition of each bit
can be polled. These bits will not be cleared following a read to this register, nor can they be written to cause an
interrupt condition.

9.21.2 ADC Overflow (ADCOvflSt)
9.21.3 Sub Overflow (SubOvflSt)

Interrupt Status (Address 61h) - Read Only
Default = 0
Function:
This bit serves as a mask for the amplifier error interrupt sources. If this bit is set, the AmpErr interrupt is
unmasked, meaning that if the AmpErr bit is set, the INT pin will go active. If the AmpErrM bit is cleared,
the AmpErr condition is masked, meaning that its occurrence will not affect the INT pin. However, the Am-
pErr and the amplifier error bits in the amplifier error status register will continue to reflect the status of the
amplifier error conditions.
Function:
This bit is read only and reflects the current lock state of the SRC. When set, indicates the SRC is currently
locked. When cleared, indicates the SRC is currently unlocked.
Function:
This bit is read only and will identify the presence of an overflow condition within the ADC. When set, in-
dicates that an over-range condition is currently occurring in the CS4525 ADC signal path and has been
clipped to positive or negative full scale.
Function:
This bit is read only and will identify the presence of an overflow condition anywhere in the Sub channel’s
signal path. When set, indicates that an over-range condition is currently occurring in the Sub channel’s
signal path and has been clipped to positive or negative full scale.
