Table 62. Power Management Register (POWER) Field Descriptions (continued)
Bit | Field | Value | Description |
3 | RESET | This bit is set when Reset signaling is present on the bus. Note: This bit is Read/Write in Host | |
|
|
| Mode, but |
2 | RESUME | Set to generate Resume signaling when the controller is in Suspend mode. The bit should be | |
|
|
| cleared after 10 ms (a maximum of 15 ms) to end Resume signaling. In Host mode, this bit is also |
|
|
| automatically set when Resume signaling from the target is detected while the USB controller is |
|
|
| suspended. |
1 | SUSPENDM | In Host mode, this bit should be set to enter Suspend mode. In Peripheral mode, this bit is set on | |
|
|
| entry into Suspend mode. It is cleared when the interrupt register is read, or the RESUME bit is set. |
0 | ENSUSPM | Set to enable the SUSPENDM output. |
