Description
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
Indicates that during a frequency change that the clock has been
driven low.
A ‘1’ indicates that the PLL is locked
Current adjustment.
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
9-bit N parameter to PLL0
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
6-bit M parameter to PLL0.
2-bit P parameter to PLL0.
1: powerdown PLL0
0: Do not bypass the DDS
1: Bypass the DDS and use the xtal (27 MHz). Normal Operating
