Number of nRF51822 high drive pins

[Tim]

The nRF51822 Product Specification says that "Maximum number of pins with 5 mA high drive is 3."

Does that mean that you can only configure 3 pins as high drive, or could I (for example) configure all pins as high-drive output, as long as no more than three of them source or sink 5 mA at any time? (And is it really 5 mA per pin, or 15 mA total? Could I have 5 pins all sourcing 3 mA each?)

[Annim]

You can drive more than 5 pins, but, at a time , only 3 pins can be at 5mA drive.

[Stefan Birnir Sverrisson]

To further clarify Annims answer, you can drive 15mA current with GPIOs at a given time, in any combination you like, 3x5mA, 15x1mA, (2x5mA + 5x1mA), doesn't matter

[Tim]

And 1x15mA? Or is it max 5mA on a single pin?

[Stefan Birnir Sverrisson]

It is max 5mA on a single pin, which is the high drive option.

can i connect set two gpio in (10mA) high drive mode and connect to buzzer does it will work fine or am excedding the maximum current limit?
