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.
“I” = Input port
“O” = Output port
Type : Composition of port in case of output port.
“C” = CMOS output
“N” = NMOS open drain output
“P” = PMOS open drain output
Op : Pull up/Pull down selection information.
“Iu” = Inner microcomputer pull up
“Id” = Inner microcomputer pull down
“Eu”= External microcomputer pull up
“Ed”= External microcomputer pull down
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.
