Table 2 Bit allocation; notes 1 and 2
Notes
1. X = don’t care.
2. In normal operation, only 8 bits are programmed into the register.
3. For normal operation, b15 to b8 do not need to be programmed.
4. The validation bit (b7) must be programmed with zero for normal operation.
5. Bit b6 is the MSB of the main divider coefficient.
6. The main divider ratio is equal to 1024 plus the programmed value (see Table 3).
Table 3 Main divider programming
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Note
1. Pins short-circuited internally must be short-circuited externally.
HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices.
