Software specifications
All the functions of the TDA7567PD are activated by I
The bit 0 of the "Address Byte" defines if the next bytes are write instruction (from µP to
TDA7567PD) or read instruction (from TDA7567PD to µP).
Chip address
1. Address selector bit, please refer to address selection description on
X = 0 Write to device
X = 1 Read from device
If R/W = 0, the µP sends 2 "Instruction Bytes": IB1 and IB2.
