When sub-code Q data is included in the input data, this data can be read together with the CRC calculation result.
To read the sub-code Q data, E/INT must be set to be selected as an interrupt output so that the sub-code Q data
When sub-code Q data is detected, the E/INT signal outputs a high level or a high-level pulse. The sub-code Q data is
The cyclic redundancy code (CRC) is a set of flags that decide whether the 80 bits of sub-code Q data is correct. Note
readout load signal can be output.
updated on each rising edge of the E/INT signal. The readout must be completed within 13.3ms (standard speed) or
6.6ms (2× speed), starting at the E/INT rising edge.
