I2C-bus controlled dual channel class-D power amplier
9.2 Data bytes
If R/W = 1, the TDF8599 sends two data bytes to the microprocessor (DB1 and DB2). All
short diagnostic and offset protection bits are latched. In addition, all bits are reset after a
read operation except the DC load detection bits (DBx[D4], DB1[D6]). The default setting
for all bits is logic 0.
In Parallel mode, the diagnostic information is stored in byte DB1.
Data byte DB1[D7] indicates whether the instruction bits have been set to logic 0. In
principle, DB1[D7] is set after a POR or when all the instruction bits are programmed to
logic 0. Pin DIAG is driven HIGH when bit DB1[D7] = 1.
