3.5 Private Peripheral Bus (PPB) memory map
The PPB is part of the defined Arm bus architecture and provides access to select
processor-local modules. These resources are only accessible from the core; other system
masters do not have access to them.

- allows auto-detection of debug components
1. The Arm Core ROM table is optionally required by Arm CoreSight debug infrastructure to discover the components on the
chip. This ROM table has no any relationship with the MCU Boot ROM.
3.6 Aliased bit-band regions
The SRAM_U, AIPS-Lite, and general purpose input/output (GPIO) module resources
reside in the Cortex-M4F processor bit-band regions.
The processor also includes two 32 MB aliased bit-band regions associated with the two
1 MB bit-band spaces. Each 32-bit location in the 32 MB space maps to an individual bit
in the bit-band region. A 32-bit write in the alias region has the same effect as a read-
modify-write operation on the targeted bit in the bit-band region.
Bit 0 of the value written to the alias region determines what value is written to the target
bit:
