SLASEM6C October 2017 – October 2020 TAS2770
Software Shutdown mode powers down all analog blocks required to playback audio, but does not cause the device to loose register state. Software Shutdown is enabled by asserting the MODE[1:0] register bits to 2'b10. If audio is playing when Software Shutdown is asserted, the Class-D will volume ramp down before shutting down. When deasserted, the Class-D will begin switching and volume ramp back to the programmed digital volume setting.
