Note: Pin No. : Terminal number of microcomputer.
Port Name : The name entered in the data sheet of microcomputer.
Symbol : Symbolized interface function.
I/O : Input or out of part.
Type : Composition of port in case of output port.
Op : Pull up/Pull down selection information.
Det : Indicates judging state of input port. Level detection is "LV"; Edge detection is "Ed"; Detection by both shifting is "E&L";
Serial data detection is "S" (Serial data output is also "S").
Res : State at reset.
STBY : State of port when STANDBY mode.
Stop : State of port when Stop mode.
