PRODUCTION DATA.
The 32-MB region from 0x4200_0000 to 0x43FF_FFFF forms the bit-band alias region for the 1MB Peripheral region. Bit-banding is a feature of the Cortex-M4 processor and allows the application to set or clear individual bits throughout the peripheral memory space without using the pipeline bandwidth of the processor to carry out an exclusive read-modify-write sequence.
NOTE
The restriction of accessing 16-bit peripherals only through byte or half-word accesses also applies to the corresponding bit-band region of these peripherals. In other words, writes to the bit-band alias region for these peripherals must be in the form of byte or half-word accesses only.
