CS4525

9.20.2

ADC Overflow (ADCOvfl)

Default = 0

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.

9.20.3

Channel X Overflow (ChXOvfl)

Default = 0

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.

9.20.4

Ramp-Up Cycle Complete (RampDone)

Default = 0

Function:

When set, indicates that all active channels have completed the configured ramp-up interval.

9.21

Amplifier Error Status (Address 62h) - Read Only

All bits in this register are considered “level-trigger” 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

Over-Current Detected On Channel X (OverCurrX)

Default = 0

Function:

When set, indicates an over current condition is currently present on the corresponding amplifier output.
