The temperature warning signals at the TAS5342DDV6EVM board are wired-OR to one temperature
warning signal (OTW – pin 22 in the control interface connector). Shutdown signals are wired-OR into one
shutdown signal (SD – pin 20 in the control interface connector).
The shutdown signals together with the temperature warning signal give chip-state information as
described in the Table
