16 bits, 256 bytes
16 bits, 256 bytes is an Esolang designed by PSTF, and his new AI friend DeepSeek-R1 671b.
It is to be not a joke, just like 6 bits, 12 bytes. It is second x-bits, y-bytes, non-joke langugage.

Overview
16 bits, 256 bytes uses a 16 bit CPU and 256 bytes memory. There is also infinity memory mode.
Charmap
We use this charmap. It is modified ASCII.

Memory type
We use registers and memory. All operations are 16-bit. We may also support variable in Unshackled dialect.
There are eight registers, they're AX, BX, CX, DX(originally A, B, C, D by DeepSeek), EX, FX, GX and HX. There are three flags. ZF indicates whether the result is 0 or not. It is a boolean value, and if the result is 0, it is true. SF is the symbol for the result. It is an integer, 1 is positive, 0 is 0, and -1 is negative. CF indicates whether a borrow or carry has occurred. CS and IP are instruction pointer, DS and DP are data. Stack may appear in future.
In assembled script, the numbers are base 16. Normal written numbers are base 10, B suffix means base 2, H means base 16(a000H is 0a000H instead, lowercase). In Unshackled dialect, you would also use decimals.
Commands
We use Shackled dialect. * means only Unshackled dialect.
Data moving
0A0B: Move the data in the register B into register A. 1ABB: Move the immediate number B to the register A. 2ABB: Move the content in memory address B to the register A. 3AAB: Move the content in register B to the memory address A.
Symbol form
MOV A, B MOV A, IMM MOV A, [B] MOV [A], B
Arithmetic
From here, data in register B is shortened by B, data in register A also becomes A.
40AB: Add B into A. May occupy four words if in Unshackled dialect. 41AB: Multiply A by B. 42AB: Multiply A by A over and over for B times. If B is 0, set A to 1. 50AB: Subtract B from A. 51AB: Divide A by B, result in integer(or float if Unshackled). 52AB: Modulo A by B. 53AB*: Get the result of A^(1/B). 54AB*: Set the value of A to the logarithm of A with B as the base. If B is not specified, it is treated as a natural base (e) by default. 550A*: Rounds A towards 0. 560A*: Rounds A away from 0. 570A*: Rounds A as usual. 600A: Increase A by 1. 700A: Decrease A by 1.
Symbol form
ADD A, B MUL A, B EXP A, B SUB A, B DIV A, B MOD A, B NRT A, B LOG A, B FLR A CEI A RND A INC A DEC A
Variable*
This chapter is only for Unshackled.
61AB: Define a variable "A" with value B. Currently only supports integer. 62AB: Set A to B.
Symbol form
LET A, B SET A, B
Logic
80AB: B = A AND B 90AB: B = A OR B a0AB: B = A XOR B b00A: A = ~A
Symbol form
AND A, B OR A, B XOR A, B NOT A
Jump
c0AA: Jump to address A with no condition. c1AA: Jump to address A if ZF is 1. c2AA: Jump to address A if ZF is 0. c3AA: Jump to address A if SF is -1. c4AA: Jump to address A if SF is 1. c5AA: Jump to address A if ZF is 1 or SF is 1. c6AA: Jump to address A if ZF is 1 or SF is -1.
Symbol form
JMP A JEQ A JNE A JLT A JGT A JGE A JLE A
Extension for Shackled
d0AB: Compare A with B, result in S. f000: Halt.
Symbol form
CMP A, B HLT
I/O
f1RP: Input R from the port P. f2PR: Output R to the port P. f3RP: Input R as character from the port P. f4PR: Output R as character to the port P. Characters are quoted in ''.
Symbol form
IN R, P OUT P, R REA R, P WRT P. R
Function*
eBAA: Allocate address A with a function named "B". Arg_list are unshackled, and code block do so. c7AA: Call the function at address A.
