FUNCTIONAL OUTLINE
Notes 1.
When using the IEBus controller, the 4.5-MHz crystal resonator cannot be used. Use the 6.3-MHz
crystal resonator.
2.
When the I
2
C bus mode is used (including when the mode is implemented in software without using
the peripheral hardware), consult NEC when ordering a mask.
