Aspects of the invention for managing power in a single chip device may comprise, an internal finite state machine that, while in a communicating state, determines from within the single chip device whether a power management status is set and/or whether a first power management event is received. If the power management status is set, the finite state machine may transition from the communicating state to a power management event sent state. If the first power management event is received, the finite state machine may transition from the communicating state to a non-communicating state. The first power management event may be a turn off power management event. Furthermore, in instances where the power management status is set, it may be cleared, thereby causing the finite state machine to transition back to the communicating state. One or more power management control registers may be utilized for indicating power management status.
