    Abstract: Implementations are disclosed for a centralized peripheral access controller (PAC) that is configured to protect one or more peripheral components in a system. In some implementations, the PAC stores data that can be set or cleared by software. The data corresponds to an output signal of the PAC that is routed to a corresponding peripheral component. When the data indicates that the peripheral is “unlocked” the PAC will allow write transfers to registers in the peripheral component. When the data indicates that the peripheral component is “locked” the PAC will refuse write transfers to registers in the peripheral component and terminate with an error.

    Abstract: A device comprising: a bus master, including a bi-directional data and clock lines, configured to produce a select signal output for enabling data transmission on the bi-directional data line to first/second different data busses supporting multiple slave devices configured to receive/transmit data over a respective data bus and to receive a clock signal from the bus master from the clock line; and a de-multiplexer including an input, first and second outputs and a control input, the input coupled to the bi-directional data line of the bus master, first/second outputs of the de-multiplexer coupled to first/second data busses, respectively, and the control input configured to receive the select signal from the bus master that is configured to communicate to a first slave device when the select signal is in a first state, and a second different slave device when the select signal is in a second different state.
