12V motor forward and reverse module

Overview

The project is based on the 12V motor forward and reverse control module of STC8G1K08 and DRV8837 motor driver chips. The physical diagram of the module is as shown below:

As shown in the picture above:

the toggle switch in the picture controls the power supply of the microcontroller and is used to reprogram the microcontroller when burning the program. Power-on.
The 4P binding post is reserved for programming, and the pin definitions are marked.
The 3P binding post is used to change the level status of the P54 pin. H is high level and L is low level. The direction of the motor is controlled by controlling the level status of this pin.
The white XH female plug on the right side is connected to the 12V motor, and there is no distinction between the positive and negative.
The black DC at the bottom is used for 12V power input. When the 2P terminal on the side is connected, the module has a point, and the lead can be connected to an external switch.

The program is provided in the attachment, please burn it yourself:

When the MOS is turned on like 2301, is the VDS voltage 0? That is, there is no loss? The simulation shows that there is no loss.
