I'm trying to figure out what is the a output current for GPIOs. The datasheet mentions that there are Types B4, B6, B8, B10 and B12 providing the corresponding output currents of 4mA, 6mA, 8mA, 10mA and 12mA. I couldn't find any other place (including the Internet) explaining what those types are. Thanks for help.
Another issues to consider is whether the port is sourcing or sinking current. DSC_DATA0 [1:0] DATA[7:0] I/O Drive strength. 00: 12mA 10: 10mA 01: 8mA 11: 6mA It seems to me that you can adjust the source or sinking capability of the port. Perhaps you can save supply current if you don't need high drive capability. HTH davef
Thanks, davef! Looks like other part of the datasheet just uses different terminology, although there is no 4mA setting, maybe they're just doing copy-paste between revisions. Some (other) CPU provide higher max switching rate when the lower drive strength is used, but in my case it's not so important, just want to make sure that it can drive e.g. a optron directly. Sergey
Where can i get more information about GPIO. Can it be Programmed as individual input/output pins. And if it can be programmed as input pins then what is the maximum current and voltage limit for the pin.
