6.2.5 System Memory Map
The NuMicro
®
NUC123 series provides 4G-byte addressing space. The memory locations
assigned to each on-chip controllers are shown in the Table 6-5. The detailed register definition,
memory space, and programming detailed will be described in the following sections for each on-
chip peripherals. The NuMicro
®
NUC123 Series only supports little-endian data format.
