Function
(PS pin = “H”)
This pin should be connected to VSS.
(PS pin = “L”)
Output Pin for Loop Filter of PLL Circuit
This pin should be connected to VSS, unless PLL Mode 15 used.
Parallel/Serial Mode Select Pin
“L”: Serial Mode, “H”: Parallel Mode
Do not change this pin during PDN pin = “H”.
Mode Setting Pin #3
Mode Setting Pin #2
Mode Setting Pin #1
(PS pin = “H”)
Mode Setting Pin #0
(PS pin = “L”)
TDM Data Input Pin
Input/Output Channel Clock Pin
When PDN pin is “L”, LRCK pin outputs “L” in master mode.
LRCK pin outputs “Hi-Z” in slave mode.
Audio Serial Data Output Pin
