Abstract:
In an embodiment, a system includes a slave circuit configured to receive an external clock signal from a master circuit, the slave circuit comprising first and second peripherals configured to receive respective clock signals obtained from the external clock signal, wherein the master circuit is configured to send to the slave circuit the external clock signal according to two different timing modes, wherein the slave circuit comprises a logic circuit configured to provide a locking signal to the first peripheral circuit when the logic circuit detects a given operating mode of the slave circuit, wherein the master circuit is configured to send the external clock signal according to a first timing mode before receipt of the locking signal, and wherein the master circuit is configured, following upon receipt of the locking signal, to send the external clock signal according to a second timing mode different from the first timing mode.
