Electronic device and charging control method

An electronic device operable with a battery, the electronic device comprising:

• a connector connectable with a cable enabling data transfer and power transfer;
• a power delivery controller that controls power transfer between the electronic device and an external device connected to the electronic device via the connector;
• a power charge/discharge circuit that controls charging and discharging of the battery;
• and
• an embedded controller that communicates with the power delivery controller and the power charge/discharge circuit, and charges the battery with a power received from the external device, wherein
• the power delivery controller
• supplies a first interrupt signal to the embedded controller to cause the embedded controller to acquire first status data including a first power reception condition, when reception of the power from the external device is started, and
• supplies a second interrupt signal to the embedded controller to cause the embedded controller to acquire second status data including a second power reception condition, when a first voltage value of the power to be received from the external device is changed by communicating with the external device, and
• the embedded controller
• acquires the first status data from the power delivery controller, when the first interrupt signal from the power delivery controller is supplied in an activation time,
• acquires a second voltage value of the power to be received from the external device from the power charge/discharge circuit, after a process associated with the first interrupt signal is completed, and
• acquires the second status data from the power delivery controller, when the first voltage value indicated by the first status data is different from the second voltage value.
