NuMicro™ NUC100 Series flash memory consists of Program memory (128/64/32KB), data flash,
ISP loader program memory, user configuration. User configuration block provides several bytes
to control system logic, like flash security lock, boot select, brown out voltage level, data flash
base address, ..., and so on. It works like a fuse for power on setting. It is loaded from flash
memory to its corresponding control registers during chip power on. User can set these bits
according to application request by writer before chip is mounted on PCB. The data flash start
address and its size can defined by user depends on application in 128KB APROM device. For
64/32KB APROM devices, its size is 4KB and start address is fixed at 0x0001_F000.
