9.1.1
The first module address MAD1 is the standard address (see Table 1).
Table 4 Slave addresses; notes 1 and 2
Notes
1. For MAD activation via external resistor: see Table 1 and Fig.23.
2. For applications without I

Table 5 Data read register (status register)
Table 6 Description of status register bits
Note
1. If no IF input is applied, then bit AFCWIN = 1 due to the fact that the VCO is forced to the AFC window border for
