    Hello,

    You will find registers information in TRM document.

    regarding teh 8s PWRON button press, this is page 289, STS_BOOT register.

    hi alexis,

    Thanks for your guidance, but my problem is when is press the push button momentarily the device will restart and if i press hold that button for 8sec or more, then also it will restart, but i want device to restart only when the button is pressed for more than 5sec. I checked for the PWRON_8S bit in STS_BOOT it is not at all setting even if i press for 8sec or more , for this bit to set what all configuration i have to make and in what all areas i have to look ( like schematic or so ) and i want to know how this 8sec time is counted by tps65950 plz explain in detail.

    Thanks

    regards

    Short press on PWRON button(more than 30ms and shorter than 8s) only generate an interrupt.

    There are multiple reason to have the PMIC shutting down before the 8s:

    1) on PWRON press, software shut down PMIC

    2) PWRON has been configured as a swiutch off event--> please check P1_SW_EVENTS register value

    3) PMIC has been configured in slave mode--> please check CFG_BOOT register value and check how the BOOT0 and BOOT1 pin are connected on the pcb
