Bit Name

Description

TOO_SLOW

This bit is set when the clock to the SRC is too slow, that is, there are not enough clock cycles to complete the

internal convolution.

OVRL

This bit is set when the left output data of the sample rate converter has gone over the full-scale range and has been

clipped. This bit is not cleared until the register is read.

OVRR

This bit is set when the right output data of the sample rate converter has gone over the full-scale range and has

been clipped. This bit is not cleared until the register is read.

MUTE_IND

Mute indicated. This bit is set when the SRC is in fast mode and clicks or pops can be heard in the SRC output data.

The output of the SRC can be muted, if required, until the SRC is in slow mode. Once read, this bit remains in its state

and does not generate an interrupt until it has changed state.

Description

OVRL Mask

Masks the OVRL from generating an interrupt.

0 = OVRL bit does not generate an interrupt.

1 = OVRL bit generates an interrupt.

OVRR Mask

Masks the OVRR from generating an interrupt.

0 = OVRR bit does not generate an interrupt.

1 = OVRR bit generates an interrupt. Reserved.

MUTE_IND MASK

Masks the MUTE_IND from generating an interrupt.

0 = MUTE_IND bit does not generate an interrupt.

1 = MUTE_IND bit generates an interrupt.
