RST_REG
Internal Reset.
0 = Normal operation.
1 = Reset of all internal logic. Output tristated during reset.
Upon completion of internal logic reset, RST_REG is internally reset to zero.
6
NewFreq
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.
5:1
N/A
Always zero.
0RECALL
Recall NVM into RAM.
0 = No operation.
1 = Write NVM bits into RAM. Bit is internally reset following completion of operation.
