Table 5.1 Setups Block
Setups data is sent from the host to the QT in a block of hex data. The block can only be loaded in Setups mode following two se quential 0x01 commands (page 12). All
devices this datasheet pertain to have the same block length. Refer also to Table 5.3, page 23 for further details, and all of Section 5.

Table 5.2 Key Mapping
Some commands return bitfields related to keys. For example, command 0x07 (report all keys) returns 3 bytes containing flag bits, one per key, to indicate which keys are reporting
touches. The following table shows the byte and bit order of the keys. The table contains the key number reported in each bit.
The key number is related to the X and Y scan lines which address each particular key. Each byte in the return stream represents one set of keys along a Y line, ie up to 8 keys.
Thus, key 0 is at location X0,Y0 and key 19 is at location X3,Y2. .
Note: Byte 0 is returned first.
