CXD2724AQ-3
(2)-2. Coefficient Data
The coefficient RAM area for Pro Logic mode is from addresses 00H to ffH (all areas). The coefficient data
consists of "fixed values" shown in Table 8-1-2 and "setting values" shown in Table 8-1-3 which can be set by
the user. All coefficient values must be sent to the coefficient RAM via the microcomputer interface.
Note that once data has been transferred to the coefficient RAM, the coefficient RAM data (00H to 7fH) is
saved unless the power is turned off, even if the RAM area is changed by setting SQD02 to SQD00 (even if
the mode is changed to Virtual mode).
• Fixed values during Pro Logic mode initialization
The following fixed values must be set in the coefficient RAM to ensure proper internal operation.
