Channel Select.
Channel value for tune operation.
If BAND 05h[7:6] = 00, then Freq (MHz) = Spacing (MHz) x Channel + 87.5 MHz.
If BAND 05h[7:6] = 01, BAND 05h[7:6] = 10, then
Freq (MHz) = Spacing (MHz) x Channel + 76 MHz.
CHAN[9:0] is not updated during a seek operation. READCHAN[9:0] provides the
current tuned channel and is updated during a seek operation and after a seek or
tune operation completes. Channel spacing is set with the bits SPACE 05h[5:4].
