Abstract: A system and method allow for overriding of a strapping option. A strapping signal places a device (e.g., a processor) in first state or mode (e.g., client or master). An override system places the device in a second state or mode. The second state or mode can be temporary. The changing of the state or mode of the device can be used to perform testing of the chip, during which a memory is written to and read from to verify operation of the chip. The second state or mode of the device may also be used to allow the device to perform alternative functions that are not available during its first state or mode.

Abstract: A system (e.g., a chip) includes first and second function blocks (e.g., function blocks) coupled to an input/output (I/O) device (e.g., a bi-directional pin or pad) via a multiplexing module. The multiplexing module can be used for both input and output of signals between the function blocks and the I/O device. Optionally, a re-clocking system is coupled to the function blocks, the I/O device, and the multiplexing module. The re-clocking system re-clocks one or more signals being input into the multiplexing module so that they are timed correctly for input or output from the system.

Abstract: Methods and systems for synchronizing a reset signal with a local clock that drives a circuit. In the circuit, the reset signal can be used to reset one or more flip-flops, memory devices, and/or logic. Sychronization of the reset signal allows the reset signal to change at an appropriate time period in relation to the lock clock signal driving the circuit. This ensures the circuit will remain stable during reset, and no data will be lost as it is processed in the circuit. Other aspects of the invention can include using a plurality of reset signals (e.g., software, hardware, local software, etc.) to form the reset signal and using a reset control system to control resets during testing of the circuit.
