This is a 44-bit integer value which is directly added (FDEC) or subtracted (FINC) from the Nx_NUM parameter when FINC or FDEC
is asserted. ClockBuilder Pro calculates the correct values for the N0 Frequency Step Word. Each N divider has the ability to add or
subtract up to a 44-bit value. The Nx_NUM register value does not change when an FINC or FDEC is performed so that the starting
point of Nx_NUM is in the Nx_NUM register.
