The subsystem driver provides a mechanism for the application to register a user-defined function that gets called within an interrupt context.
Callback functions defined in the application code must be registered with provided handlers, using the following defined API:
int XV_HdmiTxSs1_SetCallback(XV_HdmiTxSs1 *InstancePtr,
u32 HandlerType,
void *CallbackFuncPtr,
void *CallbackRef);Available handlers are defined in xv_hdmitxss1.h:
- XV_HDMITXSS1_HANDLER_CONNECT
- XV_HDMITXSS1_HANDLER_TOGGLE
- XV_HDMITXSS1_HANDLER_STREAM_UP
- XV_HDMITXSS1_HANDLER_STREAM_DOWN
- XV_HDMITXSS1_HANDLER_VS
- XV_HDMITXSS1_HANDLER_BRDGLOCK
- XV_HDMITXSS1_HANDLER_BRDGUNLOCK
- XV_HDMITXSS1_HANDLER_BRDGOVERFLOW (Debug Only)
- XV_HDMITXSS1_HANDLER_BRDGUNDERFLOW (Debug Only)
- XV_HDMITXSS1_HANDLER_FRL_CONFIG
- XV_HDMITXSS1_HANDLER_FRL_FFE
- XV_HDMITXSS1_HANDLER_FRL_START
- XV_HDMITXSS1_HANDLER_FRL_STOP
- XV_HDMITXSS1_HANDLER_TMDS_CONFIG
- XV_HDMITXSS1_HANDLER_HDCP_AUTHENTICATE
- XV_HDMITXSS1_HANDLER_DYNHDR_MWT
