Table 12. Output of PWM_SIG Outputs

Table 12 describes the exact output of the PWM_SIG output pins based on the input to the

HP_DETECT/MUTE pin and the settings of the HiZPSig, HP/Mute, BassMgr[2:0], and PWMDSel[1:0]

bits. In all configurations, the active logic input level is determined by the HP/MutePol bit.
