ST STM32F2
This article describes device specifics of the ST STM32F2 series devices. The STM32F2 devices are Cortex-M3 based MCUs with low-power functionality.

Reset
For the STM32F2 devices, the Cortex-M default reset strategy is used.
Debug specific
- If no connection can be established the J-Link will try to connect to the device via a connect under reset.
- On connect, some DBGMCU registers will be written to
- freeze the watchdogs during halt to prevent unintended resets while debugging.
- prevent the debug connection from breaking after the CPU enters deepsleep.
- When closing the J-Link connection, the DBGMCU registers are reset.
