TXPAUSEADD_2:0 |
| Operation of TX Pause Control Interface | |
|
| ||
0x0 | Transmits a PAUSE frame on every port with a pause_time = ZERO (XON) | ||
(Cancels all previous pause commands). | |||
| |||
|
| ||
0x1 | Transmits a PAUSE frame on port 0 with pause_time equal to the value programmed | ||
in the port 0 | “FC TX Timer Value ($ Port_Index + 0x07)" (XOFF). | ||
| |||
|
| ||
0x2 | Transmits a PAUSE frame on port 1 with pause_time equal to the value programmed | ||
in the port 1 | “FC TX Timer Value ($ Port_Index + 0x07)" (XOFF). | ||
| |||
|
| ||
0x3 | Transmits a PAUSE frame on port 2 with pause_time equal to the value programmed | ||
in the port 2 | “FC TX Timer Value ($ Port_Index + 0x07)" (XOFF). | ||
| |||
|
| ||
0x4 | Transmits a PAUSE frame on port 3 with pause_time equal to the value programmed | ||
in the port 3 | “FC TX Timer Value ($ Port_Index + 0x07)" (XOFF). | ||
| |||
|
| ||
0x5 to 0x6 | Reserved. Do not use these addresses. The TX Pause Control interface will not | ||
operate under these conditions. | |||
| |||
|
| ||
| Transmits a PAUSE frame on every port with pause_time equal to the value | ||
0x7 | programmed in the “FC TX Timer Value ($ Port_Index + 0x07)" for each port | ||
| (XOFF). |
