Disable internal FLASH ROM
Select this option to prevent your application to be downloaded into the microcontroller
unit’s internal FLASH ROM. You might have to use this option if the internal FLASH
ROM cannot be rewritten. This is the case, for instance, when you are using the MCU
in low power mode; typically at a clock frequency below 10,000 kHz.
By default, this option is not selected.
Debug the program using the CPU Rewrite Mode
Select this option if you are debugging the target system using the CPU Rewrite Mode.
When debugging in CPU rewrite mode, the following limitations apply:
● Address match breakpoints cannot be set
● No software breakpoints can be set in the internal ROM area.
By default, the option is not selected.
Enable the address match interrupt break function
Selecting this option stops the target application immediately before it executes an
instruction at a specified address. This mechanism uses the MCU’s address interrupt
function (that is, hardware breakpoints), so when you debug that interrupt function itself
you must deselect this option. The number of available hardware breakpoints depends
on the derivative you are using.
Overwrite data in FLASH without erasing the FLASH area block
If you select this option, writing to the flash memory area will merge the new data with
the previous flash contents, and the addresses that are not being written to will keep their
previous contents.
