Register Descriptions
4.2.14 Registers 38 and 39
CUR_UPD
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.
R [15:0]
4.2.15 Register 40
FIFO_FULL
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.
R [7:0]
4.2.16 Register 41
PH_GAIN
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.
