Figure 4-2.
Sleep Command – CRC Enabled
When the “Send Setups” command is received, the QT1111 stops measurement of QTouch
sensors and waits for 42 bytes of data to be sent. Only when all 42 bytes have been received
(and the CRC byte, if CRC is enabled), the QT1111 applies all the settings to RAM and resumes
measurement. In this case, if CRC is enabled, the CRC byte is calculated for all the data sent by
the host, including the command byte 0x01.
Control Commands are specified in detail in Section5 on page22.
4.1.5
Report Requests
Report Requests are sent by the Host to instruct the QT1111 to return status information. The
host sends the appropiate “Report Request” command, then transmits Null bytes on MOSI while
the QT1111 returns the report data on MISO.
