C-bus mode:
• If R/W = 1, the TDA8595 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 Section 7.14
• For explanation of AC and DC load detection bits, see Section 7.15 and Section 7.16
D0 fast mute all amplifier channels (mute delay 100 s)
0=no mute
1=mute
