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.
