IMPORTANT: Algorithm support for this device selection is developed. Device samples are needed for QA testing and full release in BPWin.For information on how to obtain an expedited release of this device support please contact BPM Microsystems at:Inside Sales713–688-4600inside_sales@bpmmicro.comInformation on expected socket module support can be found our web page at: http://www.www.bpmmicro.com/find-your-device/**Please note that receipt of device samples and QA testing must be completed before socket module support can be validated.Microcontroller with Flash Program Memory. The Write/Read Lock Byte at FLASH address FFFhcan be set through Device Configure menu and programmed with Secure command.In order to program Write/Read Lock Byte please enable Secure.The Lock Byte number is stored in FLASH address FFFh in ones complement’ form that isa number whose ‘0’ bits have been replaced with ‘1’s and whose ‘1’ bits have been replacedwith ‘0’s. The FLASH pages are locked starting with page 0 whichcontains FLASH addresses [0000h to 01FFh] and are locked consecutivelyfrom there. Thus it is not possible to lock the second page of FLASHwithout also locking the first page of FLASH.If any FLASH pages are locked then the FLASH page containing the LockByte is also locked. For example:To lock the first 3 pages of FLASH addresses [0000h to 05FFh]the one complement of ‘00000011b’ is ‘11111100b’ or FCh.thus write FCh to the Lock Byte address. This would alsoautomatically protect the page containing the Lock Byte addresses [E00h to FFEh].Lock byte once programmed cannot be erased. ‘
