the problem is UART4/5 don't have a registers field here https://github.com/embassy-rs/stm32-data-generated/blob/main/data/chips/STM32F100RC.json#L2675

They should have one like this https://github.com/embassy-rs/stm32-data-generated/blob/main/data/chips/STM32F100RC.json#L2896-L2900 (but probably UART, not USART)

reason is probably missing/wrong entry here https://github.com/embassy-rs/stm32-data/blob/main/stm32-data-gen/src/perimap.rs

if you could send a PR it'd be appreciated.
