That would be the right choice for those peripherals that have 16 bit registers
16 bits apart. (Though I would still use pointer arithmetic even for a.)
But IIRC, STM32F does not have such. IIRC, the 16 bit registers it has are 32
bits apart for all peripherals. At least the timers are so, with a sprinkle of
32 bit data registers for TIM2 (and some others in STM32F4). See the register
maps.
