register is valid only if the MEASUREMENT_DONE bit in
the NCO control register is set. These are NCO-related
register fields; they are used only in PLL Mode 2. The

ICLK Cycles
R [23:0]
This value is the number of ICLK cycles found within the
duration of n PCLK cycles. The value in this register is
valid only if the MEASUREMENT_DONE bit in the NCO
control register is set. These are NCO-related register
fields; they are used only in PLL Mode 2. The reset value
is 0.

NP_COUNT
R [23:0]
This value is the number of ICLK cycles found within the
duration of (n + 1) PCLK cycles. The value in this register
is valid only if the MEASUREMENT_DONE bit in the
NCO control register is set. These are NCO-related
register fields; they are used only in PLL Mode 2. The
reset value is 0.

CUR_STEP
Current NCO Loop Step
R [23:0]
This value indicates the current NCO loop step. It differs
from the programmed update step if autoacquisition 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.
