MCU CIRCUIT METHOD AND DEVICE FOR WAKING UP MASTER MCU

摘要

The present disclosure is directed to circuits, methods, and devices for waking up a master MCU so that the master MCU can receive and transmit data as it can wake up from a deep sleep state in time. The method includes: configuring a master MCU to be in a deep sleep state and configuring a peripheral interface chip and a peripheral processing chip to be in a normal operating state; Monitoring a data amount of data transmitted to a peripheral interface chip by a peripheral processing chip; And if the amount of data exceeds a threshold, sending a wake-up signal to the master MCU. With the technical solution of the present disclosure, the master MCU can wake up from the deep sleep state in time, and can receive and transmit data.
