Microcontrollers Debugger Manual

FLASH LOADCONTEX restores current buffer content into the MCU SRAM.

FLASH OVLBACKUP backups application code overlap with programming runtime/

algorithm (RAM preset for debugging). Execute the command before loading the

application/file.

FLASH OVLRESTORE restores/installs (writes in RAM) the application code overlap

with programming runtime/algorithm. Execute the command after the last FLASH

command.

FLASH PROTOCOLON displays the Flash programmer debug protocol.

FLASH PROTOCOLOFF stops displaying the Flash programmer debug protocol.

FLASH SKIPSTATUSON skips the Flash programmer device Non-Volatile Memory

blocks diagnostic. You can use this command to speed up project application loading and

programming from the IDE debug run. The Flash programmer does NOT verify that

blocks are programmed or erased.

FLASH SKIPSTATUSOFF removes the SKIPSTATUSON mode and therefore

diagnostics are performed again.

FLASH NVMFREQUENCY <frequency in Hz> specifies the Non-Volatile Memory

programming frequency in Hertz; typically the device bus speed after reset. When used,

the Flash programmer does not try to evaluate this speed and the debugger gains 2-3

seconds at application loading time. A value of “0” enables the speed detection.

FLASH NVMIF2RELOCATE Command not relevant for HCS08 devices.

FLASH NVMIF2WORKSPACE Command not relevant for HCS08 devices.

FLASH UNSECURE After device mass erasing, the Flash programmer automatically

programs the device security byte to the “Unsecure” state to enable code debugging

(default behavior).

FLASH NOUNSECURE After device mass erasing, the Flash programmer does not

program the device security byte to the “Unsecured” state. The command must be placed

in a Startup command file, to be executed before any erase operation.

TIP Use this command when the user application contains the code to program the

device security byte. This guarantees that no over-programming is performed on

the Flash security byte cell.

CAUTION If the device security byte is not programmed to the “Unsecured” state,

after the device is reset, debugging is no longer possible until the next

mass erase and security byte is programmed to “Unsecured” state.
