APROM: Stores user application program code;
LDROM: Stores Nuvoton’s ISP code or user update code;
Data Flash: It is an independent block which stores application dependent data, and reserves the data after powered off;
User Configuration: Provides control related settings, such as Flash security lock, boot select, Data Flash base address and brown-out voltage level, and is loaded from flash memory to its corresponding control registers during chip powered on.
