Does PSM_EINT have internal Pull-ups specifically in BC660K-GL?

Hi,

I’m interfacing button with PSM_EINT0 in BC660K-GL. I want to know whether this pin is internally pulled up.

In the reference design they have connected the pin via Resistor Equipped Transistor to be connected with another MCU which makes the PSM_EINT0 floating at logic 0 at base of the transistor if not pulled up internally.

Please help!

Hi,

Thanks for your reply. Though you didn’t type anything but via images you want to convey that though it’s not mentioned explicitly in the data sheet, but the pin is PSM_EINT0 has internal pull-ups.

Please confirm in YES or NO.

When you need to wake up a module, you need to pull it down through an external interrupt
