/*
* GD32VF103CB device header file.
* This is written to be as compatible as possible with STM32F1 code,
* and differences between these chips' peripherals are commented.
* Most peripherals are nearly identical, but there are plenty of
* small differences. Many of the changes seem to revolve around the
* fact that higher core clock speeds are supported (108MHz vs 72MHz).
*
* Comments about STM32F103 chips are based on the STM32F103xB
* reference manual, so they may not be comprehensive.
*
* These definitions are still very incomplete.
