Allows choosing different OSC clock frequencies for
forward channel frame.
OSC Clock Frequency in Functional Mode when OSC
2:1 Clock Source RW 0x0 mode is selected or when the selected clock source is
0x14 BIST Control not present e.g. missing PCLK/ External Oscillator. See
Table 3 for oscillator clock frequencies when PCLK/
External Clock is missing.
