9.20.2 ADC Overflow Interrupt (ADCOvfl)
9.20.3 Channel Overflow Interrupt (ChOvfl)
9.20.4 Amplifier Error Interrupt Bit (AmpErr)
cause this bit to be set. This interrupt bit is an edge-triggered event and will be cleared following a read
of this register.
If this bit is set, indicating a SRC state change condition, and the SRCLockM bit is set, the INT pin will go
active. To determine the current lock state of the SRC, read the SRCLockSt bit in the interrupt status reg-
ister.
Function:
This bit is read only. When set, indicates that an over-range condition occurred anywhere in the CS4525
ADC signal path and has been clipped to positive or negative full scale as appropriate since the last read
of this register. This interrupt bit is an edge-triggered event and will be cleared following a read of this
register.
If this bit is set, indicating an ADC over-range condition, and the ADCOvflM bit is set, the INT pin will go
active. To determine the current overflow state of the ADC, read the ADCOvflSt bit in the interrupt status
register.
Function:
This bit is read only. When set, indicates that the magnitude of an output sample on channel 1, 2, or the
Sub channel has exceeded full scale and has been clipped to positive or negative full scale as appropriate
since the last read of this register. This interrupt bit is an edge-triggered event and will be cleared following
a read of this register.
If this bit is set, indicating a channel over-range condition, and the ChOvflM bit is set, the INT pin will go
active. To determine the current overflow state of each channel, read the ChXOvflSt and SubOvflSt bits
in the interrupt status register.
Function:
This bit is read only. When set, indicates that an error was detected in the power amplifier section since
the last read of this register. This interrupt bit is an edge-triggered event and will be cleared following a
read of this register. This bit is the logical OR of all the bits in the amplifier error status register. Read the
amplifier error status register to determine which condition occurred.
