Memory mapping

The peripheral address mapping has been changed in the STM32F0 series versus

STM32F1 series. The main change concerns the GPIOs which have been moved from the

APB bus to the AHB bus to allow them to operate at the maximum speed.

Table 8 provides the peripheral address mapping correspondence between STM32F0 and

STM32F1 series.
