Function
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.
“H”
= Outputs High Level at reset
“L”
= Outputs Low Level at reset
“Z”
= Becomes High impedance mode at reset
STBY
: State of port when STANDBY mode.
“O/L” = Output port and “L”
“I”
= Input port
Stop
: State of port when Stop mode.
“O/L” = Output port and “L”
“I”
= Input port
