Description
These bits are reserved and should be written with zeros.
The Synthesizer A Counter register is used for diagnostic purposes and is not recommended for normal operation.
The Channel register is the recommended method of setting the Synthesizer frequency.
The Synthesizer A Count along with the Synthesizer N Count can be used to generate the Synthesizer frequency. The
range of valid values of the Synthesizer A Count is 0 through 31. Using the Synthesizer A and N Count register is an
alternative to using the Channel register. Selection between the use of the Channel register or the A and N registers
is done through the Channel register (Reg 0x21, bit 7). When in Channel mode the A and N Count bits can be used
to read the A and N values derived directly from the Channel.
Description
This bit is reserved and should be written with zero.
The Synthesizer N Counter register is used for diagnostic purposes and therefore is not recommended for normal
operation. The Channel register is the recommended method of setting the Synthesizer frequency.
The Synthesizer N Count along with the Synthesizer A Count can be used to generate the Synthesizer frequency. The
range of valid values of the Synthesizer N Count is 74 through 76. Using the Synthesizer A and N Count register is
an alternative to using the Channel register. Selection between the use of the Channel register or the A and N registers
is done through the Channel register (Reg 0x21, bit 7). When in Channel mode the A and N Count bits can be used
to read the A and N values derived directly from the Channel.
