NCO-Related Registers
4-15
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.
4.2.11 Registers 29, 30, and 31
N_COUNT
ICLK Cycles
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.
R [23:0]
4.2.12 Registers 32, 33, and 34
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.
4.2.13 Registers 35, 36, and 37
CUR_STEP
Current NCO Loop Step
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.
