Bit 30 – LOCK DPLL Locked Interrupt Status (cleared by writing ASRC_MR.ASRCENx=0)

Bit 16 – SECE Security and/or Safety Event Interrupt Status (cleared on read)

Value	Description
0	No security or safety event has occurred since the last read of ASRC_ISR.
1	One or more safety or security events have occurred since the last read of ASRC_ISR. For details on the event, refer to ASRC_WPSR.

Bit 13 – TXOVR Transmit Over Flow Interrupt Status (cleared on read)

Bit 12 – TXUDR Transmit Under Flow Interrupt Status (cleared on read)

Bit 11 – TXCHUNK Transmit FIFO Chunk Interrupt Status (cleared automatically when the input FIFO has fewer samples than configured in ASRC_CH_CONF.CHUNKx)

Bit 10 – TXFULL Transmit FIFO Full Interrupt Status (cleared automatically when ASRC starts converting data)

Bit 9 – TXEMPTY Transmit FIFO Empty Interrupt Status (cleared when writing in ASRC_THRx)

Bit 8 – TXRDY Transmit Ready Interrupt Status (cleared automatically when input FIFO is full)

Bit 5 – RXOVR Receive Over Flow Interrupt Status (cleared on read)

Bit 4 – RXUDR Receive Under Flow Interrupt Status (cleared on read)

Bit 3 – RXCHUNK Receive FIFO Chunk Interrupt Status (cleared automatically when the output FIFO has fewer samples than configured in ASRC_CH_CONF.CHUNKx)

Bit 2 – RXFULL Receive FIFO Full Interrupt Status (cleared by reading ASRC_RHRx)

Bit 1 – RXEMPTY Receive FIFO Empty Interrupt Status (cleared automatically when ASRC has converted one sample)

Bit 0 – RXRDY Receive Ready Interrupt Status (cleared automatically when ASRC has converted one sample)
