DESCRIPTION
NOT reset input (active low, resets digital circuitry)
AC link Data slot select.
Low = Normal stereo (slots 3,4),
High = Surround (slots 7,8),
High impedance (Z) = LFE and centre (slots 6,9)
Digital positive supply
Clock crystal connection or clock input (XTAL not used)
Clock crystal connection
Serial data input
Serial interface clock output to AC-link controller if ID pin held
low (WM9709 is master).
Serial interface clock input from AC-link master if ID pin held
either high or high impedance (WM9709 is slave).
Digital ground supply
Serial data output to AC-link controller
Serial interface sync pulse from AC-link controller
Analogue ground supply, chip substrate
No internal connection
No internal connection
Reference input/output; internal divider generates midrail
No internal connection
Main analogue output for left channel
Main analogue output for right channel
No internal connection
Analogue positive supply
Analogue ground supply, chip substrate
