In CMOS ICs, a latch-up phenomenon is caused when an voltage exceeding VCC or an voltage below VSS is

applied to input or output pins or a voltage exceeding the rating is applied across VCC and VSS.

When a latch-up is caused, the power supply current may be dramatically increased causing resultant thermal

In using the external clock, drive X0 pin only and leave X1 pin unconnected.

In products with multiple V CC or VSS pins, the pins of a same potential are internally connected in the device to

Accessing RAM space with the above instruction does not cause any problem.

In the device, there are internal registers which is initialized only by a power-on reset. To initialize these registers,
