You can shift and And in Ada but a better way is to create a memory overlay

https://github.com/AdaCore/Ada_Drivers_Library/blob/master/arch/ARM/STM32/svd/stm32f7x/stm32_svd-rng.ads

Then you can flip a bit with:

RNG_Device.CR.RNGEN := True;

It also allows only providing access when using the overlay library to 3 bits of
a 4 bit register (within a 32 bit register) via named enums etc.. Which is
really nice. Writing 32 bits if required is catered for by

with Volatile_Full_Access;

A program, called svd2ada can generate the overlays for your particular micro
but they are really useful created by hand in drivers and protocols and would be
for Linux too.
