from the documentation of the ADSP21261, I see that it is capable of driving only some micro-amperes from output pins (FLAGS0-15, e.g.)
I understand from the diagram (Fig. 28 in ADSP21261 data sheet) that in current sink mode, it is possible to "drive" up to 30 mili-amperes at 3.3V.
1. are these 30 mili-amperes valid for every single pin or for a group of pins? E.g. 30 mili-amperes for every single Flag pin?
2. is it a recommended design to use multiple LEDs in current sink mode ? Or should a buffer be used in current source mode as e.g. in the EZ-Kit lite?
