Hello team,

In our design , we use P0/P1/P8/P32 as ADC input and Pull resistance to each pin of value 33K to Vcore (Vcore is active during Sleep).

When processor enters Sleep mode, Low power current is around ~500uA.

But when we isolate GPIO P0, from the pull up, then low power current drops to ~50-60 uA

Could any suggest, what could be reason?

Why P0 seems to leak current?

Any recommended configuraiton ?

THanks nad regards,

hari

There are no special requirement on P0 although some folks here suggested a 10K pull-up. Did you still see this is deep-sleep?
