Description

Keep Alive mode control

Fields

KEEP_ALIVE_EN

Global enable for USB_KEEP_ALIVE mode
OWN_OVERRD_EN

When set to 1, during KEEP_ALIVE mode, if received token is not SETUP, the OWN bit of current BD will be forced to 0, so usb core will response with NAK
STOP_ACK_DLY_EN

When set to 1, will respond the ipg_stop when usb core state is idle and no AHB transfer; when set to 0, will respond the ipg_stop when no AHB transfer

0 (0): Enter KEEP_ALIVE mode until the USB core is idle and there is no USB AHB transfer.

1 (1): Enter KEEP_ALIVE mode immediately when there is no USB AHB transfer.
AHB_DLY_EN

Must be set to 1 to delay the first USB AHB bus transfer until after the USB has exited KEEP_ALIVE mode

0 (0): Do not delay the USB AHB transfer if the USB AHB transfer occurs while exiting KEEP_ALIVE mode.

1 (1): Delay the USB AHB transfer until the clock is recovered, if the USB AHB transfer occurs while exiting KEEP_ALIVE mode.
