NCO-Related Registers
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.
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.
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.
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.
