Battery Bounce

Hello,

我力量ing the DA14531 with a small coin cell battery. Sometimes when I plug in the battery it appears that the processor does not boot up or is stuck in reset. I am wondering if it is experiencing the same battery bounce issue as the DA14585 processor? How do you suggest mitigating the issue since the DA14531 doesn't have a dedicated Reset pin. The reset pin is currently being used as the MOSI signal to the external flash.

Thanks,

Jeff
