Abstract:
1. A microcontroller comprising: a first circuit module configured to operate in an active mode and a static mode; a first control circuit coupled to the first circuit module, the first control circuit configured to select between the active mode and the static mode for the first circuit module; a second circuit module configured to perform an operation susceptible to interference from the first circuit module when the first circuit module is operating in the active mode; and a second control circuit coupled to the second circuit module, the second control circuit configured to cause the second circuit module to perform the operation; wherein the first control circuit is configured to detect an event signal, select the static mode for the first circuit module, and propagate a ready signal; wherein the second control circuit is configured to detect the ready signal, perform the operation, and propagate an end signal after the second circuit module completes performance of the operation; and wherein the first control circuit is configured to detect the end signal and select the active mode of operation.
