CXD3003R

• Input coefficient inversion when SFID = 1 and THID = 1

The preset coefficients for the TRK filter are negative for input and positive for output. With this, the error input

and servo that outputs reversed phase drive can be hypothesized.

When SFID = 1, the TRK filter negative input coefficient is applied to the SLD filter, so invert the SLD input

coefficient (K00) code. (For example, inverting the code for coefficient K00: E0h results in 60h.)

For the same reason, when THID = 1, invert the TRK hold input coefficient (K40) code.
