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.

9.21.1 SRC State Transition (SRCLockSt)

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.

SRCLockSt Setting

SRC Lock State

0 .......................................... SRC is currently unlocked.

1 .......................................... SRC is currently locked.

9.21.2 ADC Overflow (ADCOvflSt)

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.

ADCOvflSt Setting

ADC Overflow State

0 .......................................... An ADC overflow condition is not currently present.

1 .......................................... An ADC overflow condition is currently present.

9.21.3 Sub Overflow (SubOvflSt)

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.

SubOvflSt Setting

Sub Overflow State

0 .......................................... An overflow condition is not currently present on the Sub channel.

1 .......................................... An overflow condition is currently present on the Sub channel.

9.21.4 Channel X Overflow (ChXOvflSt)

Function:

These bits are read only and will identify the presence of an overflow condition anywhere in the associated

channel’s signal path. When set, indicates that an over-range condition is currently occurring in the chan-

nel’s signal path and has been clipped to positive or negative full scale.

ChXOvflSt Setting

Channel X Overflow State

0 .......................................... An overflow condition is not currently present on channel X.

1 .......................................... An overflow condition is currently present on channel X.
