34.6.3.4 Quick Command

Setting the Quick Command Enable bit in the Control B register (CTRLB.QCEN) enables quick command. When quick command is enabled, the corresponding Interrupt flag (INTFLAG.SB or INTFLAG.MB) is set immediately after the client acknowledges the address. At this point, the software can either issue a Stop command or a repeated start by writing CTRLB.CMD or ADDR.ADDR.

Important: The use of the Quick Command mode (CTRLB.QCEN = 1) is only allowed if SCL Stretch Mode is CTRLA.SCLSM=0 which makes the Quick Command feature not available in High-Speed mode.
