Hello @siva4
Please, consider that JN5189/88T is preferred for any new Zigbee, Thread design.
As I understand, you are trying to use a DIO to wake the device after putting it to sleep, is this correct? If that is so, please take a look at the JN516x Integrated Peripherals API User Guide, Section 5.2 DIO Interrupts and Wake-up. This section explains how the DIOs configured as inputs can be used to generate System Controller interrupts; these interrupts can be used to wake the microcontroller, if it is sleeping.
By any change, does your application implement wireless functionalities? JN51xx Core Utilities User Guide provides a reference for software utilities that may be incorporated in Zigbee 3 applications. Chapter 3 Power Manager (PWRM) describes the Power Manager module, which manages the transition of the JN51xx device into and out of low-power modes.
Regards,
Eduardo.
