ADVANCE INFORMATION
3.12.Command Language
The TPU supports a command language, allowing the
TV controller to start complex processing inside the
TPU with simple commands. The TV controller is not
burdened with time consuming tasks like page search-
ing or data shuffling.
The application software has to send commands to the
TPU via I2C bus using the command subaddresse
SUB4 (see Section 3.14.1.3. on page 83).
Table 3–15 lists all available commands. For a more
detailed description of the command language see
Table 3–16.
