Memory model

This section describes the processor memory map, the behavior of memory accesses, and
the bit-banding features. The processor has a fixed memory map that provides up to 4 GB of
addressable memory.
The regions for SRAM and peripherals include bit-band regions. Bit-banding provides
atomic operations to bit data, see
The processor reserves regions of the Private peripheral bus (PPB) address range for core
peripheral registers, see
page 193.
