SAMC21 8/16 bit access to 32 bit registers how/why? - EEVblog

It's all about code size and speed optimization (and in some cases, atomicity as well!) You can write 4 bytes with 8-bit write instructions, but ...

How different are 8-bit microcontrollers from 32-bit ... - TI E2E

And as a second great advantage, 32-bit MCUs can cover their whole address range with one register - 8-bit MCUs cannot, and 16-bit MCUs only when staying within ...

Quick basic questions about microcontrolers/microprocessor 8/16/32 ...

Some registers might be 16 bits in length. In that case, the 16-bit register is accessed as two bytes, LO-byte and HI-byte. A 32-bit MCU ...

16-Bit MCUs are Alive and Well - Renesas

With less overhead, a smaller instruction set, and fewer registers, 16-bit MCUs consume less power overall than a comparable 32-bit device.

Why do CPUs start executing code in 16-bit mode? - Quora

Why As others have said, this is only true of x86 CPUs, not CPUs in general. It's not even true of (quite) all x86 CPUs.
