MAINTAINING INPUT AND/OR OUTPUT CONFIGURATION AND DATA STATE DURING AND WHEN COMING OUT OF A LOW POWER MODE

摘要

come from a low-power mode when the semiconductor integrated circuit device enters a low-power mode that appears when you input / output (I / O) to wake up and re-initialize the logic circuit to recover the previous logic state of the internal registers without disrupting the configuration control and status data. Therefore, does not interfere with the operation of other devices connected to the semiconductor integrated circuit device in a low power mode before. When all the internal logic and the register in the semiconductor integrated circuit devices are re-initialized, - may come out of a "low-power state and the wake-up recovery" signal. This signal is an integrated circuit device is entering a low power mode when the I / O keeper is the I / O configuration data and control states are stored in the cell returns the control to return to the logic circuits, and / or the internal register in the semiconductor integrated circuit device shows that it is possible.
