Peripheral Memory Map - NXP Semiconductors freescale KV4 Series Reference Manual

Peripheral Memory Map

The bitbanding functionality supported by the processor core uses aliased regions that
map to the basic RAM and peripheral address spaces. This functionality maps each 32-bit
word of the aliased address space to a unique bit in the underlying RAM or peripheral
address space to support single-bit insert and extract operations from the processor.
System 32-bit Byte Address Range
0x0000_0000–0x0003_FFFF
0x0004_0000–0x01FF_BFFF
0x1FFF_C000–0x1FFF_FFFF
0x2000_0000–0x2000_3FFF
0x2000_4000–0x21FF_FFFF
0x2200_0000–0x23FF_FFFF
0x2400_0000–0x2FFF_FFFF
0x3000_0000–0x33FF_FFFF
0x3400_0000–0x3FFF_FFFF
0x4000_0000–0x4007_FFFF
0x4008_0000–0x400F_EFFF
0x400F_F000–0x400F_FFFF
0x4010_0000–0x41FF_FFFF
0x4200_0000–0x43FF_FFFF
0x4400_0000–0xDFFF_FFFF
0xE000_0000–0xE00F_FFFF
0xE010_0000 - 0xFFFF_FFFF
5.3 Peripheral Memory Map
The peripheral memory map is accessible via one slave port on the crossbar in the
0x4000_0000–0x4007_FFFF region. The device implements one peripheral bridge that
defines a 512 KB address space.
AIPS 0 is located on slave port 2, the address space is 0x4000_0000–0x4007_7FFF. For
programming model accesses via the peripheral bridges, there is generally only a small
range within the 4 KB slots that is implemented. Accessing an address that is not
implemented in the peripheral results in a transfer error termination.
