iRiver

GPIO

GPIO1

"*" indicates that this GPIO or function is actually implemented by two pins on the physical package -- one dedicated input pin and one dedicated output. This means that this logical bit can serve two functions simultaneously. There's only one bit that decides function vs. GPIO, so the composite pin must either both be function pins or a GPI and GPO pin.

"(C)" indicates that it is confirmed

There is an (obsolete) similar table at IriverMemoryMap which includes information on where in the original firmware you can find usage of these pins.
