6.16 Setups Block
Table 6.1 Setups Table
Setups data is sent from the host to the QT using the I 2C interface. The setups block is memory mapped onto this interface. Thus each setup can be accessed by
reading/writing the appropriate address. Setups can be accessed individually or as a block. Before writing to any setup, an unlock code (value 0x55) must be written to the
setups write unlock address (130). Refer also to Table 6.2, page 22 for further details, and all of Section 6.
