*2: The pins to be connected to the controller (CE, CL, DI, INH) can handle 3V.
*3: In RC oscillator operating mode, an external resistor, Rosc, and an external capacitor, Cosc, must be connected
between the OSC pin and ground. If external clock operating mode is selected, a current protection resistor, Rg (4.7
to 47 kΩ), must be inserted between the external clock output pin (on the external oscillator) and the OSC pin.
(See the “OSC Pin Peripheral Circuit” section.)
*4: When a capacitor except the recommended external capacitance (Cosc = 1000pF) is connected to the OSC pin, it
should be in the range 220 to 2200pF.
