9.2 Device addressing
9.3 Register addressing
The data transfer mode is characterized by signal L3MODE = HIGH and is used to
transfer one or more bytes representing a register address, instruction or data.
Basically, two types of data transfers can be defined:
The device address consists of one byte with:
Table 13:
After sending the device address (including DOM bits), indicating whether the information
is to be read or written, one data byte is sent using bit 0 to indicate whether the
information will be read or written and bits 1 to 7 for the destination register address.
Basically, there are 3 methods for register addressing:
DOM
1. Addressing for write data: bit 0 is logic 0 indicating a write action to the destination
2. Addressing for prepare read: bit is logic 1, indicating that data will be read from the
3. Addressing for data read action. Here, the device returns a register address prior to
