35 / 47 page  – 35 – CXD2720Q-2 14. Filter Coefficient Table [Relevant coefficients] DC1a1 (address = 05H), DC1a0 (address = 06H), DC1b (address = 07H), DC2a1 (address = 08H), DC2a0 (address = 09H), DC2b (address = 0AH), PEQa (address = 0BH), PEQb1 (address = 0CH), PEQb2 (address = 0DH), PEQg (address = 0EH), HCa1 (address = 4BH), HCa0 (address = 4CH), HCb (address = 4DH), IIR∗b (address = 62, 65, 68, 6BH), IIR∗a1 (address = 60, 63, 66, 69H), IIR∗a0 (address = 61, 64, 67, 6AH) The cut-off frequencies and PEQ gain, Q, and center frequency settings for each signal flow filter are shown in Tables 14-1 (1) to 14-5 (3). Note) • If the above setting values are changed during DSP operation, the output level becomes unstable for several 1/fs. • The coefficients differ depending on fs used. Please inquire with regard to use at fs other than this value.
