Document Type and Number:
WIPO Patent Application WO/2022/114120
Kind Code:
A1
Abstract:
Provided is electric equipment which enables rewriting of a program using an existing connection terminal. With a view to enabling writing of a program in a ROM area of an MCU 50 from a writing device by using an existing terminal that is provided for connection to a battery pack 100, a connection circuit on the side of electric equipment 1 is changed so as to have an energization circuit 61, a first communication circuit 62, and a reset control circuit 63. When a writing device 300 is connected to the electric equipment 1 by using an adapter 200, power supply for operating the MCU 50 is fed from the energization circuit 61 so as to start up the MCU 50 and a reset operation is performed by the reset control circuit 63, and then writing of a program in a ROM area of the MCU 50 is performed by an external writing device via the first communication circuit 62. Meanwhile, none of the three circuits 61-63 mentioned above have any adverse effect on normal operation of the electric equipment when the battery pack 100 is mounted.
