0 = PLL closed
1 = PLL open
0 = internal V
1 = external V
0 = invert ASCLK, ALRCLK edges triggered by falling edge of ASCLK
1 = don’t invert ASCLK, ALRCLK edges triggered by rising edge of ASCLK
0 = invert AMXCLK, ASCLK edges triggered by falling edge of AMXCLK
1 = don’t invert AMXCLK, ASCLK edges triggered by rising edge of AMXCLK
