Приложение A2. Карты регистров STM32F4

Регистры и биты основных блоков STM32F4 — из заголовка STM32F407, по которому написан слой F4 в каждом разделе. Заголовки F4 новее и щедрее: назначение каждого регистра и описание каждого бита — из их собственных комментариев, смещения — по структурам *_TypeDef. У каждого блока отмечено, есть ли он в STM32F401 (Nucleo): часть блоков F407 — ЦАП, CAN, Ethernet, контроллер внешней памяти — там отсутствует.

Как читать: смещение — от базового адреса блока; 31:16 — поле битов с 16 по 31; одно число — отдельный бит. Цифра в скобках у заголовка блока — раздел, где блок разобран.
