If bit R/W = 1, the TDA8594 sends four data bytes to the microprocessor: DB1, DB2,
DB3, and DB4
All bits except DB1[D7] and DB3[D7] are latched.
All bits except DBx[D4] and DBx[D5] are reset after a read operation. Bit DBx[D2] is
set after a read operation; see
For explanation of AC and DC load detection bits; see
