WDOG1 pin  (IMx6UL)

I am using imx6 ul for the hardware design. The datasheet provides option for wdog1 (LCD_reset pad) pin. All the wdog stuff is generally done in software.  Reference manual says wdog1  is a global watchdog signal. Is WDOG1_ANY pad is for detecting reset external signal to reset cpu?  Is it optional in hardware design? 

 

What does WDOG EXTERNAL SIGNAL mean? Are pin connection required to the chip from external source like reset IC?
