Bit 11 – DMAEIF DMA Bus Error Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | DMA bus error has occurred |
| 0 | DMA bus error has not occurred |
Bit 10 – PKTCOMPIF DMA Buffer Descriptor Processor Packet Completion Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | DMA BD packet is complete |
| 0 | DMA BD packet is in progress |
Bit 9 – BDDONEIF DMA Buffer Descriptor Done Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | DMA BD process is done |
| 0 | DMA BD process is in progress |
Bit 8 – CONTHRIF Control Buffer Threshold Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | The control buffer has more than THRES words of space available |
| 0 | The control buffer has less than THRES words of space available |
Bit 7 – CONEMPTYIF Control Buffer Empty Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | Control buffer is empty |
| 0 | Control buffer is not empty |
Bit 6 – CONFULLIF Control Buffer Full Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | Control buffer is full |
| 0 | Control buffer is not full |
Bit 5 – RXTHRIF Receive Buffer Threshold Interrupt Flag bit
Note: In the case of Boot/xIP mode, the POR value of the receive buffer threshold is
zero. Therefore, this bit will be set to a '
1',immediately after a
POR until a read request on the System Bus bus is received.| Value | Description |

| 1 | Receive buffer has more than RXINTTHR words of space available |
| 0 | Receive buffer has less than RXINTTHR words of space available |
Bit 4 – RXFULLIF Receive Buffer Full Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | Receive buffer is full |
| 0 | Receive buffer is not full |
Bit 3 – RXEMPTYIF Receive Buffer Empty Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | Receive buffer is empty |
| 0 | Receive buffer is not empty |
Bit 2 – TXTHRIF Transmit Buffer Threshold Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | Transmit buffer has more than TXINTTHR words of space available |
| 0 | Transmit buffer has less than TXINTTHR words of space available |
Bit 1 – TXFULLIF Transmit Buffer Full Interrupt Flag bit
| Value | Description |
|---|---|
| 1 | The transmit buffer is full |
| 0 | The transmit buffer is not full |
Bit 0 – TXEMPTYIF Transmit Buffer Empty Interrupt Flag bit
| Value | Description |
|---|---|
