Please follow the steps below to add a breakpoint in Debug mode:
- Use Ctrl+B to open the Breakpoints dialog box.
- Enter a register address or an address in RAM into the “Expression” field of the Breakpoints dialog box.
- Enable the “Read” or “Write” option, specify the “Size” as 4 for a register, and enable “Bytes” in the “Access” section.
- Click the “Define” button to add a new breakpoint.
Taking the M051 series for example, to see if the value of the UA_THR register of UART0 is written, follow the steps as shown in the figure below:
Note1: The “Count” setting could not be changed to control the hit count of breakpoints.
Note2: Up to two breakpoints can be set for a register.
