6.3.6.12 Interrupts

An I2SMCC interrupt request can be triggered whenever one or several of the following bits are set in I2SMCC_ISRA and/or I2SMCC_ISRB:

• Receive Left x Ready (RXLRDYx)
• Receive Right x Ready (RXRRDYx)
• Receive Left x Overrun (RXLOVFx)
• Receive Right x Overrun (RXROVFx)
• Transmit Left x Ready (TXLRDYx)
• Transmit Right x Ready (TXRRDYx)
• Transmit Left x Underrun (TXLUNFx)
• Transmit Right x Underrun (TXRUNFx)
• Write Error (WERR)

The interrupt request is generated if the corresponding bit in the Interrupt Mask registers (I2SMCC_IMRA and I2SMCC_IMRB) is set. Bits in I2SMCC_IMRx are set by writing a ’1’ to the corresponding bit in I2SMCC_IERx and cleared by writing a ’1’ to the corresponding bit in I2SMCC_IDRx. The interrupt request remains active until the corresponding bit in I2SMCC_ISRx is cleared.
