List all peripherals defined in an ARM CMSIS SVD file. Returns each peripheral's name, base address, and description. Use this to discover what hardware blocks are available in a microcontroller.

Get full details for a specific register within a peripheral, including address offset, size, access type, reset value, and all bit-fields with their positions. Use this when you need exact register layout for low-level firmware code.

Describe a specific bit-field within a register: its bit offset, width, access type, and enumerated values if defined. Use this when you need to understand or set a specific control bit or flag.

Search across all peripherals and registers in an SVD file using a case-insensitive substring match. Returns up to 10 matches with peripheral name, register name, and description. Use this when you know part of a register name but not which peripheral it belongs to.
