Register Descriptions
Current NCO Loop Update Step
This value indicates the current NCO loop update step. It
differs from the programmed update step if autoacquisi-
tion is enabled. The registers are read-only. These are
NCO-related register fields; they are used only in PLL
Mode 2. The reset value is 0.
FIFO Fullness Indicator
This value is a sign representation of the virtual FIFO
fullness used for the NCO loop regulation. These are
NCO-related register fields; they are used only in PLL
Mode 2. The reset value is 0.
Phase Regulation Gain
This value sets the gain used during phase regulation.
The real value applied is multiplied by four. These are
NCO-related register fields; they are used only in PLL
Mode 2. The reset value is 0b0001 0000.
