21 / 26 page ![]() 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. 20 Range is in 100ms increments; 0 = disable, 1 = 100ms, default = 1s 10 24 8 0...255 DHT Drift Hold Time 1 253 8 20 Range is in 100ms increments; 1 = 100ms.
