This bit should read 0 in normal operation.
New Frequency Applied.
Alerts the DSPLL that a new frequency configuration has been applied. This bit will
clear itself when the new frequency is applied. Write 0x40 to this register to assert
NewFreq.
Freezes the M Control Word.
Prevents interim frequency changes when writing RFREQ registers.
Freezes the VCDADC Output Word.
May be used to hold the nominal output frequency of the Si599. Do not use with Si598.
Always zero.
Recall NVM into RAM.
0 = No operation.
1 = Write NVM bits into RAM. Bit is internally reset following completion of operation.
