)

int e_po3030k_apply_timer_config	(	int	pixel_row,
		int	pixel_col,
		int	bpp,
		int	pbp,
		int	bbl
	)

Modify the interrupt configuration

Warning:

This is an internal function, use e_po3030k_config_cam

Parameters:

	pixel_row	The number of row to take
	pixel_col	The number of pixel to take each pixel_row
	bpp	The number of byte per pixel
	pbp	The number of pixel to ignore between each pixel
	bbl	The number of row to ignore between each line

Returns:

Zero if OK, non-zero if the mode exceed internal data representation
