WM8962
THREED_LHPF_MODE register bit. This is typically used to filter out fixed-frequency noise or
resonances.
The 3D Surround High-Pass / Low-Pass filter can be programmed using the THREED_LHPF_COEFF
register field (R270). For the derivation of this parameter, refer to the WISCE^TM configuration tool
supplied with the WM8962 Evaluation Kit.
