Edit Question
Title
Body
I've done some researching on bit addressable microcontrollers. The only one that came across in my path is the Intel MCS-51( wiki page ) which is still used very commonly today... I was wondering if you can directly address a bit in C, for example on the SFR region wiki 8051 memory architecture . The bits that I address in the SFR, are they bit addressed directly, or is it a bitwise operation in a bitfield that is byte addressed or is it something else completely? Specifically, from here: Check if a single bit is set , it looks like the bit is directly manipulated with a MOV, I'm wondering if this is possible in C (with extensions) or does it only look like bitwise operation, but in the background there are some compiler stuff that uses bytes only? As a follow up question, are there any bit addressable modern processors?
