All supply pins have to be decoupled, with two capacitors: one for the high frequencies (approximately 1 nF) and one for the low
frequencies (approximately 100 nF or higher). If a capacitor of 39 nF between pins CZ and CP is not available, use a higher one
as close as possible to this value. Resistors R1 and R2 must be connected: the recommended value is 10 k .
