+Description:
+		Stores channel Y frequency resolution/channel spacing in Hz for PLL
+		devices. The given value directly influences the operating mode when
+		fractional-N synthesis is required, as it derives values for
+		configurable modulus parameters used in the calculation of the output
+		frequency. It is assumed that the algorithm used to compute the various
+		dividers is able to generate proper values for multiples of the channel
+		spacing.
