When selecting alternative function for one pin, set the PIPCn.PIPCnm
bit to 1 to enable direct IO mode control (the alternative function
decides the pin direction) and disable input buffer and bidirection
control functionalities (PIBCn.PIBCnm = 0 and PBDCn.PDBCnm = 0) intially
enabled when configuring the pin in PORT mode
