Micronas
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.
Table 3–15 lists all available commands. For a more
detailed description of the command language see
Table 3–16.
The application software has to send commands to the
TPU via I
2
C bus using the command subaddresse
SUB4 (see Section 3.14.1.3. on page 83).
