Hi-Z PWM_SIG Outputs (HiZPSig)
Default = 0
Function:
When cleared, the PWM_SIG1 and PWM_SIG2 output drivers are placed in a high-impedance state.
When set, the PWM_SIG1 and PWM_SIG2 output drivers are active. It should be noted that the function
of the PWM_SIG outputs is determined by the PWMDSel[1:0] bits in Register 04h.
Bass Cross-Over Frequency (BassMgr[2:0])
Default = 000
Function:
Controls the operation and cross-over frequency of the bass manager. See
page 35
Enable Channel B Parametric EQ (EnChBPEq)
Default = 0
Function:
Enables the parametric EQ bi-quad filters for channel B.
Enable Channel A Parametric EQ (EnChAPEq)
Default = 0
Function:
Enables the parametric EQ bi-quad filters for channel A.
