Information Required to Unsecure the
Device
To unsecure a device, the debugger needs to know the value of the FCDIV register to
correctly mass erase the device and program the security byte. The “Information required
to unsecure the device” dialog box provides an FCDIV value to the Unsecure Command
File script. To access this dialog box, select the menu option HCS08 Open Source BDM >
Command Files and click on the Unsecure tab.
