I can’t find a certain pin on OSD335x-BAS/IND datasheet even though it is there on the AM335x. Do you support this function?

All the peripherals supported by the AM335x are also supported by the OSD335x-BAS/IND.  However, the OSD335x-BAS/IND only supports 3.3V I/Os. Please refer to question ‘What are the differences in ball maps of AM335x and OSD335x?‘ for ball map differences between OSD335x and AM335x.
