②Toolbar area:                               provides convenient operation entrances for common functions.
③Burning configuration area:         used to select the target chip type, Flash operation initial address,
                                                        CLK frequency and other parameters.
④Chip information display area:    used to display the target chip UID, version number, Flash size,
                                                        read protection status information.
⑤Firmware display area:                used to display the full path name of the selected target firmware.
⑥Chip Flash read configuration and content display area:
                                                         used to set the initial address, length and other parameters of the

(1) After clicking all the buttons mentioned later, the WCH-Link connection communication will be
        automatically performed, and there is no need to click this button first. This button is mainly
        used to clear the chip information display area and FLASH content display area.
(2)    When introducing all the functions described later, WCH-Link has been updated to the latest
        firmware and all hardware connections are normal by default.
(3)    The read protection needs to be released before chip information reading, erasing, programming,
        verification, reset, and Flash content reading operations.

3.3. Read Target Chip Information
Click “Target->Query Chip Info” in menu or icon in toolbar, or “Alt+F3” shortcut key.

The operation result shows ,means the read is successful, and chip will return UID, version number and Flash size parameter. The corresponding data will display.

4. Operate Target Chip Read Protection Status
