-The PAC is the lowest API for accessing peripherals and registers, if you don't count reading/writing directly to memory addresses. It provides distinct types to make accessing peripheral registers easier, but it does not prevent you from writing unsafe code.
+The PAC is the lowest API for accessing peripherals and registers, if you don't count reading/writing directly to memory addresses.
