CONTROL COMMANDS
DS2490 Control commands are used to control the processing of Communication commands/data and can
also be used to issue a device Reset. As listed in Table 11 there are 11 Control commands. The USB
control transfer setup packet coding to transmit these commands is detailed in Appendix 1. Like Mode
commands, Control commands are immediately processed by the DS2490 when they are received.
