Configuration Steps to Enable the Blink Mode

Disable SLCD and disable all the previous running modes as given in xpro_lcd_clear_all()
First make the segments ON which needs to be blinking by using the xpro_lcd_blink_icon_start() or xpro_lcd_show_text() function
Disable the blink mode by writing a '0' to the Blink bit in Control C register (CTRLC.BLINK)
Write the blink mode by Blinking Mode bit (BCFG.MODE)
Write the required “Blink Segment Selection x” bits (BCFG.BSSx) if blink selected mode is configured
Write the frame counter x index to the Frame Counter Selection bits in the BCFG register (BCFG.FCS)
Write the appropriate configuration for the Blink mode mentioned in the above parameters by using the function slcd_blink_set_config() to blink all the segments, or slcd_set_blink_pixel() to blink the selected segments only
Disable the frame counter using the function slcd_disable_frame_counter(FCx). (Optional, not needed if already configured.)
Write the configurations of the frame counter associated with this mode in FCx.OVF and FCx.PB by using the function slcd_set_frame_counter(FCx,0,0x1) and enable it by using the function slcd_enable_frame_counter(FCx). (Optional, not needed if already configured.)
Enable the blink mode by writing a '1' to the Blink bit in Control C register (CTRLC.BLINK)

Note:

The BCFG register cannot be written when blink is enabled. The blink frequency can be modified, before that the selected frame counter has been disabled.
