Power-on reset
In order to avoid an undefined state when the power is switched ON, the devices have an internal reset circuit which sets
the standby mode (oscillator OFF).

TABLES OF INPUT AND OUTPUT
The specified output tones are obtained when a 3.579545 MHz crystal is used.
In each table, the logical states for the input data lines are related to voltage levels as follows:
1 = HIGH = V
DD
0 = LOW = V
SS
X = don’t care
