ALRCLK
Two binary divided signals ASCLK and ALRCLK are provided for slower serial digital audio signal transmission and for
channel-select. The frequencies of these signals are defined by the following parameters:
SDIV[5:0] 38H[5:0] according to the equation:

THER CONTROL SIGNALS
Further control signals are available to define reference clock edges and vertical references:
APLL[3AH[3]]; Audio PLL mode:
0: PLL closed
1: PLL open
AMVR[3AH[2]]; Audio Master clock Vertical Reference:
0: internal V
1: external V
LRPH[3AH[1]]; ALRCLK Phase
0: invert ASCLK, ALRCLK edges triggered by falling edge of ASCLK
1: don’t invert ASCLK, ALRCLK edges triggered by rising edge of ASCLK
SCPH[3AH[0]]; ASCLK Phase:
0: invert AMXCLK, ASCLK edges triggered by falling edge of AMXCLK
1: don’t invert AMXCLK, ASCLK edges triggered by rising edge of AMXCLK.
