STM32F030 PC13,14,15 current sink limits?

Is it OK to use these pins as current sinks for driving LEDs ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Nice pun! :)

Great question too!
