Abstract:
1. An apparatus, comprising: a control module with a power output, a clock output, a wait output, and a standby input; an initiator module with a power input coupled to the power output of the control module, a clock input coupled to the clock output of the control module, a wait input coupled to the wait output of the control module, and a standby output coupled to the standby input of the control module, wherein the initiator module is configured to automatically detect an idle condition of the initiator module and to automatically transmit a standby signal to the control module in response to detecting the idle condition; wherein the initiator module is configured to automatically enter a standby mode after transmitting the standby signal to the control module; wherein the standby mode allows the initiator module to continue communicating with the control module while preventing the initiator module from initiating communication with other modules; wherein the control module is configured to automatically transmit a wait signal to the initiator module in response to receiving the standby signal from the initiator module; wherein the initiator module is configured to automatically deactivate the standby signal in response to detecting a wakeup event; wherein the control module is configured to deactivate the wait signal in response to detecting that the standby signal has been deactivated; wherein the initiator module is configured to transition from the standby mode to a normal mode in response to detecting that the wait signal has been deactivated; and wherein the normal mode allows the initiator module to initiate communication with the other modules.
