ARM Cortex M cpus may be programmable in "pure" C, but that as more to do with startup and exception handling than instruction set architectures.
AVRs are moderately C-friendly, despite some obnoxious departures from PDP11 styles.

(I'd have to check carefully to remember whether the PDP11 had explicit stack instructions, or whether they just 'fell out' of having the PC be accessible as a register, and the "standard" addressing modes.) The 8051 is not particularly C-friendly, and the 8bit PICs are pretty awful (non-contiguous data memory ouch!) (although, it might be interesting to see how the added PIC18 instructions really DO help C), but a lot of early 8-bit machines were better - there were credible C compilers for Z80/8080-class machines as early as the late 70s, for example.

Usually that means at least one "index register" capable of accessing the full address space, some addressing modes useful for accessing frames via the index register, and some aids to implementing stacks. While many regard the PDP11 architecture as particularly elegant, vendors have been claiming their chips had "pdp-11-like architectures" since the 68. Memory and speed-wise, a modern 8051 should be on-par with an early PDP11 or LSI11. Let's not get carried away the PDP11 was a 16bit machine with a 64kbyte address space and 8 registers.

I hope my question is understandable! If not, I will gladly elaborate and maybe post all the code (although it is quite messy). Is what I am attempting to do possible? Sending a single Pin adress as an overload for a method? If so, what datatype should it be? I was juggling between char and bit but I can't settle. I know I'm not doing this right, but I had to start somewhere. Then, on my main method, I run something like while(TRUE) So, this is not working. I already have sbit R1 = P1^0 all through the needed inputs, but I'm not sure if this is correct. However, the way I wanted to do this was by making a unique scroll method that received the row parameter and set it to HIGH accordingly. Basically, the input is a 3x3 Button Matrix which I want to utilize by scanning through the rows with a pulse while checking the columns for a connection pretty basic. Hello, EEVB Community! I'm currently making a very simple Tic-Tac-Toe game with an AT89C51RC2 and I am having issues getting the button input right.
