‘repeat start condition’ —In a communication, the master can generate multiple start conditions to complete multiple message exchanges, and finally generate a stop condition to end the entire communication process. Since there is no stop condition during the period, the master keeps occupying the...
Master send out STOP or Repeated START(go back to step1) Normally if everything works fine, the system will work smoothly within the requirement of protocol. Timing and other design aspects must be took into consideration to guarantee the whole bus' condition. Clock Synchronization and Bus Arbit...

After this time, the NCT218 resets the SDA line back to its idle state (high impedance) and waits for the next start condition. However, this feature is not enabled by default. Bit 7 of the consecutive alert register (Address = 0x22) should be set to enable it. Addressing the Device ...
