A simple Subleq computer emulator with assembler.
Debug Serial IO
A: 0x0000 → 0x00 (0)
B: 0x0000 → 0x00 (0)
Program Counter: 0x0000

The Subleq Emulator is an 8 bit processor with 16 bit little endian addressing.
The processor's 16 bit address space allows up to 65536 (64K) bytes of memory.
Since instructions are comprised of 3 addresses and an address takes 2 bytes, each instruction is 6 bytes in size.
The maximum number of instructions is about 10920 when accounting for memory mapped peripherals.
The program counter starts at address 0, the instruction here should be just a jump to allow address 0 to be empty.
reading/writing to certain memory addresses interfaces with alu hardware
$ffff: write to data lines, read 0
$fffe: read from data lines
$fffd: read/write to "register" a
$fffc: read/write to "register" b
$fffb: read a xor b
$fffa: read a and b
$fff9: read a or b
$fff8: read not a
$fff7: read a << 1
$fff6: read a >> 1
