DETECTING WAKE-UP EVENTS FOR A CHIP BASED ON AN I/O POWER SUPPLY |
摘要 |
A device is provided that includes a chip having a processor and wake-up logic. The device also includes power management circuitry coupled to the chip. The power management circuitry selectively provides a core power supply and an input/output (I/O) power supply to the chip. Even if the power management circuitry cuts off the core power supply to the chip, the wake-up logic detects and responds to wake-up events based on power provided by the I/O power supply.
