Abstract
Certain aspects of reducing power consumption in communication devices may comprise deasserting a signal indicating that an on-chip UART may be ready to receive data. The deasserted signal may be asserted when the on-chip UART is not ready to receive data. The deasserted signal and asserted signal may be a RTS signal or a CTS signal. The signal may be deasserted when an on-chip processor wakes up from a low power state. The deasserted signal may be asserted when an on-chip processor enters a low power state. The on-chip UART may be adapted to receive and process data from an off-chip processor when the signal is deasserted. The data may be queued externally to the on-chip UART by an off-chip processor when the deasserted signal is asserted. The on-chip UART may be adapted to receive an interrupt signal that causes it to wake up from a low power state.
