SYS_NIRQ/GPIO_0

Other Parts Discussed in Thread: TPS65950

What is the real use of this SYS_NIRQ line? In the TRM it is given as it is triggered from TWL4030 for wake-up event. Can we use this for MADC, RTC, Power Management interrupt interrupt from TWL4030 using GPIO_0?

Can anyone clear this...

    The OMAP35xx sys_nirq input can go directly into the OMAP35xx Interrupt Controller (INTC).  The OMAP35xx TRM mentions a use can be for a wake-up event.  If you connect the OMAP35xx sys_nirq input to the TPS65950 INT1 output, there are a number of potential sources for interrupts including the RTC, USB presence, Charger presence, etc.
