Get Instructions
Get instructions are instructions that read the data from a location in the QT1110 memory map.
Figure 4-7.
Positive Recalibration Delay Get Instruction – CRC Disabled
The host sends the appropriate “Get” command, followed by a “Null” byte. The QT1110 returns
the contents of the addressed memory location.
Figure 4-7 on page 15 shows the exchange for a report on the positive recalibration delay
(assuming that the data byte is 0x0C).
With CRC Enabled, this exchange takes 4 bytes, with a command CRC transmitted by the host
and a report CRC returned by the QT1110 (see Figure 4-8).
