+        help
+          Specify the target rate the internal DAC should try to match. This
+          will use PLL1 to generate a frequency as close as possible to this
+          rate.
+
+          Must be within the range 32000 to 50000, which should be suitable to
+          generate most other frequencies in power of 2 steps.
+
+          Ex:
+                48000 will also suit 24000 and 12000
+                44100 will also suit 22050 and 11025
+                32000 will also suit 16000 and 8000
