Table 2 Explanation of Table 1
Address selection
The module address contains the programmable address bits MA1 and MA0, which offer the possibility of having
up to 4 synthesizers in one system. The relationship between MA1 and MA0 and the input voltage at pin AS is given in
Table 3.
Table 3 Address selection
Note
1. This address is selected by connecting a 15 k resistor between pin AS and pin V
Status at Power-On Reset (POR)
At power-on or when the supply voltage drops below approximately 2.75 V internal registers are set according to Table 4.
Table 4 Status at Power-on reset; note 1
Notes
1. X = don’t care.
2. At Power-on reset, all output ports are in high-impedance state.
