One example relates to a device that includes an activity monitor. The activity monitor includes a bus interface having inputs coupled to receive signals from a bus and having outputs coupled to provide signals to an other device. The activity monitor monitors the bus for a message directed to a predefined address that is associated with the other device in response to detecting that the other device is a low power sleep mode, the activity monitor outputs the predefined address to the other device to enable the other device to capture the predefined address, via the bus interface, in response to the monitored address matching the predefined address that is associated with the other device.

Digital bus activity monitor

An apparatus is provided. The apparatus comprises a polynomial register having a plurality of bits, a first bus, a second bus, and a transceiver that is coupled to the first bus, the second bus, and the polynomial register. The polynomial register is configured to store a user-defined polynomial, and the transceiver includes a pseudorandom bit sequence (PRBS) generator is configured to generate a scrambled signal from the user-defined polynomial and a PRBS checker that is configured to generate a descrambled signal from a second signal using the user-defined polynomial.

Flexible PRBS architecture for a transceiver

An apparatus is provided. A polynomial register having a plurality of bits is provided, where the polynomial register is configured to store a user-defined polynomial. A transceiver is coupled to a first bus, a second bus, and the polynomial register. The transceiver includes a self-synchronous scrambler that is configured to generate a scrambled signal from a first signal using the user-defined polynomial and a self-synchronous descrambler that is configured to generate a descrambled signal from a second signal using the user-defined polynomial.
