uSD_Frame();

Usage:
var := uSD_Frame();

Description:
After a pointer to a valid video has been set with uSD_SetSector(), calling this function shows each video/animation frame sequentially, returning the number of frames remaining. The position of the video is specified at the current origin which is set with gfx_MoveTo() function. 
 
This function should be used for playing video/animation clips where the application requires to service other tasks such as monitor button presses or serial commands in between frames.  Using the uSD_Video() function will tie up the proccessor for the duration of the clip which maybe undesirable specially if the clip is lengthy. After setting up the video sector location and its position on the screen, as described above, the uSD_Frame() function can be called within a loop and the returned remainder frame count can be used as the loop exit parameter. After each call (at the end of frame display), other tasks can also be called and serviced.

Parameters:
None.

Return values:
Returned value is the number of frames remaining of the video/animation clip.
