... QT501 or QT511), and ‘0’ means the device is a linear type (e.g. QT411, or QT401). There are 5 commands as follows. 3.3.1 0x00 - Null Command The Null command will trigger a new acquisition (if /SS rises), otherwise, it does nothing. The response to this command is the Standard Response byte, returned on the next SPI shift. 7 QT411-ISSG R6.01/1005 ...
