摘要

The chip controlling an external device eg a floppy disc drive, monitors its own operating state and switches itself into a lower power consumption state when the chip determines that it is in a predetermined state from which it can power down cleanly. The power down operation is transparent ie the chip appears no different to the external device than when it operates at full power. Non-core activities such as the oscillator operation can be maintained when the chip is in the power down state. <IMAGE>
