means the appropriate build and pin configuration options have been selected.
References to an enabled feature means one that has also been configured by software.
1.5.3 Architecture and protocol information
The processor complies with, or implements, the specifications described in:
• ARM architecture
• Advanced Microcontroller Bus Architecture
• Debug Access Port architecture.
This TRM complements architecture reference manuals, architecture specifications,
protocol specifications, and relevant external standards. It does not duplicate
information from these sources.
ARM architecture
The processor implements the ARMv6-M architecture profile. See the ARMv6-M ARM.
Advanced Microcontroller Bus Architecture
The system bus of the processor implements AMBA-3 AHB-Lite. See the ARM AMBA
3 AHB-Lite Protocol Specification.
Debug Access Port architecture
The Debug Access Port (DAP) is an optional component, defined by v5.1 of the ARM
Debug interface specification, see the ARM Debug Interface v5 Architecture
