— Power terminal. Supply +3.3 V.
Output enable terminal for microcomputer serial communication. When using tri-state buffer externally, activates
O
by this terminal. When outputs "MSDATO", "L" is shown.
O Output ready flag for microcomputer serial communication. When completing, outputs "L". Open drain.
O Data output terminal for microcomputer serial communication. Hi-Z except for output.
Data input terminal for microcomputer serial communication. Inputs data and address with serial from
I
microcomputer.
Shift clock input terminal for microcomputer serial communication. Imports and shifts serial input data by setting up
