TAPNUM[6:0]: TAP Specifying for Programmable FIR Filter Coefficient Readback
Specify the TAP when readback the coefficient set to the programmable FIR filter <Address 0x38,
0x39>.
R_COEF[15:0]: Programmable FIR Filter Coefficient Readback (Readback Only)
Readback the coefficient set to the programmable FIR filter.
The coefficient that is specified by <Address 0x37> TAPNUM[6:0] bits is readback.
