LC78622NE
22. Reset Circuit; Pin 58: RES
When power is first applied, this pin should be briefly set low and then set high. This will set the muting to –∞ dB
and stop the disk motor.

Setting the RES pin low sets the LC78622NE to the settings enclosed in boxes in the table.
23. Other Pins; Pin 2:TAI, pin 64: TEST1, pin 11: TEST2, pin 32: TEST3, pin 33: TEST4, pin 62: TEST5, pin 59:
TST11
These pins are used for testing the LSI’s internal circuits. Even though pull-down resistors are built into the TAI and
TEST2 to TEST5 input pin circuits, these pins must be connected to 0 V during normal operation. TST11 is an output
pin and should normally be left open. Since TEST 1 is an input pin without a pull-down resistor built in, be sure to
connect to 0V.
