FMAC: Filter Math Accelerator Base address of the input buffer (X1) within the internal memory (0x00 to 0xFF). Number of 16-bit addresses allocated to the input buffer (including the optional "headroom"). Number of 16-bit addresses allocated to the input buffer (including the optional "headroom"). Input threshold: the buffer full flag will be set if the number of free spaces in the buffer is inferior to this threshold. HeadRoom value of Input Buffer. Base address of the coefficient buffer (X2) within the internal memory (0x00 to 0xFF). Base address of the coefficient buffer (X2) within the internal memory (0x00 to 0xFF). Number of 16-bit addresses allocated to the coefficient buffer. Number of 16-bit addresses allocated to the coefficient buffer. Base address of the output buffer (Y) within the internal memory (0x00 to 0xFF). Base address of the output buffer (Y) within the internal memory (0x00 to 0xFF). Number of 16-bit addresses allocated to the output buffer (including the optional "headroom"). Number of 16-bit addresses allocated to the output buffer (including the optional "headroom"). Output threshold: the buffer empty flag will be set if the number of unread values in the buffer is inferior to this threshold. HeadRoom value of output buffer. [IIR only] Coefficient vector A. Coefficient vector B. Coefficient vector B. Size of the coefficient vector A. Size of the coefficient vector B. Size of the coefficient vector B. Access to the input buffer (internal memory area): DMT, IT, Polling, None. Access to the output buffer (internal memory area): DMA, IT, Polling, None. Enable or disable the clipping feature (wrapping when the q1. Filter type. Filter type. Length of the coefficient vector B. Length of the coefficient vector A. The gain to be applied to the accumulator output. The value output to the Y buffer is multiplied by 2^R Length of the coefficient vector B.
