Devices, systems and methods for controlling electrical loads in one or more areas. A method includes transmitting, with a microcontroller via a transceiver, a sync packet including a unique address of the lighting fixture control module to a bus. The method includes listening, via the transceiver, on the bus. The method includes placing the microcontroller into a master operation mode when a master sync timeout period expires without receiving a second sync packet including a unique address for a second master device from the bus. The method includes placing the microcontroller into a subordinate operation mode when the second sync packet is received from the bus during the master sync timeout period.

A system having a first mode, a second mode and a system bus comprises a peripheral circuit, a power management unit (PMU), an additional wire and a control module. The peripheral circuit has a configuration information representing a circuit state thereof. The power management unit (PMU) generates an interrupt signal. The additional wire transmits therethrough the interrupt signal. The control module, in response to the interrupt signal, stores the configuration information via the system bus when the system is in the first mode and restores the configuration information via the system bus when the system is in the second mode.

A method includes, in response to a master port requesting bus access for a bus transfer with a slave port, selecting the master port to allow a master device that is coupled to the master port to perform a bus transfer with a slave device that is coupled to the slave port. The bus transfer is associated with at least one bus cycle. The method includes, in response to an end of the bus transfer, maintaining selection of the master port for at least one additional bus cycle.
