Texas Instruments TAS5110D6REF - Manual (Page 13)

PCB Key Map
1-5 Introduction
- H-bridge outputs (OUTPUTA and OUTPUTB) are in a high-impedance
state (Hi-Z state).
- ERR_RCVY at the PWM processor is forced low by the SHUTDOWN
signal.
- RESET at the TAS5110 is forced low by the VALID signal.
- The VALID signal goes high after 4 ms and then the TAS5110 starts
switching again.

The autorecovery loop is closed when the TAS5110D6REF board is
connected to the TAS5026REF or TAS5036REF module.
