The PCA9549 provides eight bits of high speed TTL-compatible bus switching controlledby the I2C-bus. The low ON-state resistance of the switch allows connections to be madewith minimal propagation delay. Any individual A to B channel or combination of channelscan be selected via the I2C-bus, determined by the contents of the programmable Controlregister. When the I2C-bus bit is HIGH (logic 1), the switch is on and data can flow fromPort A to Port B, or vice versa. When the I2C-bus bit is LOW (logic 0), the switch is open,creating a high-impedance state between the two ports, which stops the data flow.An active LOW reset input (RESET) allows the PCA9549 to recover from a situationwhere the I2C-bus is stuck in a LOW state. Pulling the RESET pin LOW Resets the I2C-busstate machine and causes all the bits to be open, as does the internal power-on resetfunction.

The PCA9548A is an octal bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individualSCx/SDx channel or combination of channels can be selected, determined by thecontents of the programmable control register.An active LOW reset input allows the PCA9548A to recover from a situation where one ofthe downstream I2C-buses is stuck in a LOW state. Pulling the RESET pin LOW Resets theI2C-bus state machine and causes all the channels to be deselected as does the internalPower-on reset function.

This program demonstrates using watchdog timers to invoke deadline handlers. CoordinatorTask sends data to the organizer. OrganizerTask receives data from the coordinatorTask, and Resets the coordinatorTask when no data is sent by the coordinatorTask in the past five seconds (deadline time). This demonstration program is automatically stopped after twenty seconds.
