[1] After cold or warm reset, the AClink interface is active with MLNK bit reset.

[2] I/OC = CMOS bidirectional; ID = digital input; S = supply; OA = analog output; IC = CMOS input;

IA = analog input; I/OA = analog bidirectional; OC = CMOS output.

[3] BIT_CLK is an input for AClink secondary codec, an output for primary codec. When BIT_CLK is an

output, the XTAL oscillator is active.

[4] SDIN is driving a 0 until a valid SYNC framing signal is received after cold reset.
