BCFS[3]
PL[0] and BCFS[4:1] are status bits which means they are READ ONLY bits in this register. Any write to these bits
will be ignored. FSRATE[5], CLK1544EN[6], and PLLM[7] are READ/WRITE bits.
With an external 8 kHz Frame Sync set (PCMFS:FSS=0), PLL Bit Clock Frequency Status, BCFS[3:0] bits will show
the value of BCLK according to the following table. Not all clocks are supported by 16KHz frame sync [
