NUC950ADN
32-BIT ARM926EJ-S BASED MCU
Except On-Chip Peripherals, the start address of each memory bank is not fixed. You can use bank control
registers to assign a specific bank start address by setting the bank’s base pointer (13 bits). The address
resolution is 256K bytes. The bank’s start address is defined as “base pointer << 18”, and the bank’s size is
“current bank size”. (EXT0CON ~ EXT2CON)
The CPU booting start address is fixed at address 0x0000_0000 after reset or power-on. In the event of an
access request to an address outside any programmed bank size, an abort signal is generated. The
maximum accessible memory size of each external IO bank is 4MB@8bit (8MB@16bit and 16MB@32bit), and
128M bytes on SDRAM banks.
