NB Programmable FIR API Programming
Same with Rx PFIR, a profile pre-defined set of NB PFIR coefficients (customized NB PFIR coefficients will be supported in the later
software release) are automatically loaded during chip initialization, there is no need for baseband processor to call any PFIR coefficients
loading API function.
