Variables

volatile U16 g_usb_event
 Public : U16 g_usb_event usb_connected is used to store USB events detected upon USB general interrupt subroutine Its value is managed by the following macros (See usb_task.h file) Usb_send_event(x) Usb_ack_event(x) Usb_clear_all_event() Is_usb_event(x) Is_not_usb_event(x).
U8 g_usb_mode
 Public : (U8) g_usb_mode Used in dual role application (both device/host) to store the current mode the usb controller is operating /.
U8 remote_wakeup_feature
 Public : (U8) remote_wakeup_feature Store a host request for remote wake up (set feature received) /.
volatile U8 private_sof_counter
 Private : (U8) private_sof_counter Incremented by host SOF interrupt subroutime This counter is used to detect timeout in host requests.
volatile U8 otg_features_supported
U8 otg_user_request
