Functions

Internal routines to manage asynchronous interrupt pin change

This interrupt is connected to a switch and allows to wakeup CPU in low sleep mode.

This wakeup the USB devices connected via a downstream resume.

static void ui_enable_asynchronous_interrupt (void)
 Initializes and enables interrupt pin change. More...
 
static void ui_disable_asynchronous_interrupt (void)
 Disables interrupt pin change. More...
 
static void UI_WAKEUP_HANDLER (void)
 Interrupt handler for interrupt pin change. More...
 
Main user interface functions
void ui_init (void)
 Initializes the user interface. More...
 
void ui_usb_mode_change (bool b_host_mode)
