Queue 0 Transmit Debug Register
| TXQPAUSED | Transmit Queue in Pause When this bit is high and the Rx flow control is enabled, it indicates that the Tx Queue is in the Pause condition (in the full-duplex only mode) because of the following: Reception of the PFC packet for the priorities assigned to the Tx Queue when PFC is enabled Reception of 802.3x Pause packet when PFC is disabled 0 (Val_0x0): Transmit queue in pause status is not detected 1 (Val_0x1): Transmit queue in pause status is detected |
| TRCSTS | MTL Tx Queue Read Controller Status This field indicates the state of the Tx Queue Read Controller: 0 (Val_0x0): Idle state 1 (Val_0x1): Read state (transferring data to the MAC transmitter) 2 (Val_0x2): Waiting for pending Tx status from the MAC transmitter 3 (Val_0x3): Flushing the Tx Queue because of the packet abort request from the MAC |
| TWCSTS | MTL Tx Queue Write Controller Status When high, this bit indicates that the MTL Tx Queue Write Controller is active, and it is transferring the data to the Tx Queue. 0 (Val_0x0): MTL Tx Queue write controller status is not detected 1 (Val_0x1): MTL Tx Queue write controller status is detected |
| TXQSTS | MTL Tx Queue Not Empty Status When this bit is high, it indicates that the MTL Tx Queue is not empty and some data is left for transmission. 0 (Val_0x0): MTL Tx Queue not empty status is not detected 1 (Val_0x1): MTL Tx Queue not empty status is detected |
| TXSTSFSTS | MTL Tx Status FIFO Full Status When high, this bit indicates that the MTL Tx Status FIFO is full. Therefore, the MTL cannot accept any more packets for transmission. 0 (Val_0x0): MTL Tx Status FIFO full status is not detected 1 (Val_0x1): MTL Tx Status FIFO full status is detected |
| PTXQ | Number of Packets in the Transmit Queue This field indicates the current number of packets in the Tx Queue. When the ETH_MTL_OPERATION_MODE[DTXSTS] bit is set to 1, this field does not reflect the number of packets in the Transmit queue. |
| STXSTSF | Number of Status Words in Tx Status FIFO of Queue This field indicates the current number of status in the Tx Status FIFO of this queue. When the ETH_MTL_OPERATION_MODE[DTXSTS] bit is set to 1, this field does not reflect the number of status words in Tx Status FIFO. |
