^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) Description:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 		Stores channel Y frequency resolution/channel spacing in Hz.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		The value given directly influences the MODULUS used by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		the fractional-N PLL. It is assumed that the algorithm
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		that is used to compute the various dividers, is able to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		generate proper values for multiples of channel spacing.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) Description:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		Sets channel Y REFin frequency in Hz. In some clock chained
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 		applications, the reference frequency used by the PLL may
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 		change during runtime. This attribute allows the user to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 		adjust the reference frequency accordingly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 		The value written has no effect until out_altvoltageY_frequency
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		is updated. Consider to use out_altvoltageY_powerdown to power
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 		down the PLL and its RFOut buffers during REFin changes.
