Abstract: An electronic device includes a non-volatile memory. Operations for reading data from the memory are performed in response to a first clock signal. Operations for writing data to the memory are performed in response to a second clock signal which is different from the first clock signal. The first clock signal is generated by an oscillation circuit of the electronic device, and the second clock signal is generated external to the electronic device (for example through a communications interface).

A method includes obtaining a clock-data swap check command; determining, based on processing the clock-data swap check command, that an external clock-data swapped state is present at an external clock port of a WM and an external data port of the WM, wherein the external clock port is coupled to a first external serial signal and the external data port is coupled to a second external serial signal; and selecting, based on determining that the external clock-data swapped state is present at the external clock port and the external data port, an internal clock-data swapped configuration for a crossbar circuit. The crossbar circuit is selectably configurable to couple the WM in an internal clock-data swapped configuration or couple the WM in an internal clock-data non-swapped configuration.
