Microcontroller with Flash Program Memory. The Write/Read Lock Byte at FLASH address 1FFFh can be set through Device Configure menu and programmed with Secure command. The Lock Byte number is stored in FLASH address 1FFFh in ones complement’ form that is a number whose ‘0’ bits have been replaced with ‘1’s and whose ‘1’ bits have been replaced with ‘0’s. The FLASH pages are locked starting with page 0 which contains FLASH addresses [0000h to 01FFh] and are locked consecutively from there. Thus it is not possible to lock the second page of FLASH without also locking the first page of FLASH. If any FLASH pages are locked then the FLASH page containing the Lock Byte 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 also automatically protect the page containing the Lock Byte addresses [1E00h to 1FFEh]. The only way to remove the protection is executing a Chip Erase operation. ‘
BPM does not sell programmable devices, nor do we program devices directly. BPM makes programmers and accessories to make programming in-house fast, easy, and profitable.
