TDA7563PD

10

SOFTWARE SPECIFICATIONS

The bit 0 of the "ADDRESS BYTE" defines if the next bytes are write instruction (from

µP to TDA7563PD) or

read instruction (from TDA7563PD to

µP).

Chip Address:

X = 0 Write to device

X = 1 Read from device

If R/W = 0, the

µP sends 2 "Instruction Bytes": IB1 and IB2.

Table 6. IB1

Table 7. IB2

If R/W = 1, the TDA7563PD sends 4 "Diagnostics Bytes" to

µP: DB1, DB2, DB3 and DB4.
