Part Number: DP83849I

PWRDOWN_INT_A should float/suspend, but the default function for this pin is POWER DOWN. Is there a problem with the use of device functions at this time?

Thanks

Hi Shitong,

The PWDDOWN_INT_A (Pin 18) functions as POWER DOWN by default. It has an internal pull up resistor and this pin is active-low. If this pin is going to be unused, it is okay to leave it floating. This will not cause a problem with the device.

Regards,

Alvaro
