Registers:

		
			r0 - r15: General purpose registers (use these for whatever)
ax: Accumulator (stores the result of the last computation)
flags: Flags (flags of the last computation)
tmp: Temporary (used by instructions)
Initial value: 0 / 0b / 0h
		
	

Instructions:

		
			ldi <loc>, <val>: Load immediate (<loc> = <val>) -- example: ldi %r7, 25 (r7 = 0x19)

add <v1>, <v2>, <loc>
Addition (<loc> = <v1> + <v2>)
example: add %r9, 74, %r4 (r4 = r9 + 74)

sub <v1>, <v2>, <loc>
Subtraction (<loc> = <v1> - <v2>)
example: sub %ax, %r14, %r6 (r6 = ax + r14)

mul <v1>, <v2>, <loc>
Multiplication (<loc> = <v1> * <v2>)
example: add %r9, 74, %r4 (r4 = r9 * 74)

orr <v1>, <v2>, <loc>
Bitwise OR (<loc> = <v1> || <v2>)
example: orr %r5, 66, %r2 (r2 = r5 || 66)

and <v1>, <v2>, <loc>
Bitwise AND (<loc> = <v1> && <v2>)
example: and %r3, %ax, %r10 (r10 = r3 && ax)

xor <v1>, <v2>, <loc>
Bitwise XOR (<loc> = <v1> ^ <v2>)
example: orr %r11, %r12, %r5 (r5 = r11 ^ r12)

not <val>, <loc>
Bitwise NOT (<loc> = ~<val>)
example: and %ax, %r9 (r9 = ~ax)

lsh <val>, <loc>
Left Shift (<loc> = <val> << 1)
example: lsh %r3, %r6 (r3 = r6 << 1)

rsh <val>, <loc>
Right Shift (<loc> = <val> >> 1)
example: rsh %r4, %r8 (r8 = r4 >> 1)

coi <val>
Console Integer (print(int(<val>)))
example: con %r1

col <val>
Console Letter (print(chr(<val>)))
example: col %r12

theres no jump instructions because its not meant to do that    

inc <loc>
Increment (<loc>++)
example: inc %r7 (r7++)
coded: ...
ldi %tmp, 1
add <loc>, %tmp, <loc>

dec <loc>
Decrement (<loc>--)
example: dec %r4 (r4--)
coded: ...
ldi %tmp, 1
add <loc>, %tmp, <loc>

neg <loc>
Negate (<loc> = -<loc>)
example: neg %r13 (r13 = -r13)
coded: ...
ldi %tmp, 0
sub %tmp, <loc>, <loc>

cmp <v1>, <v2>
Compare
example: cmp %ax, %r14
coded: ...
ldi %tmp, 0
sub <v1>, <v2>, %tmp
		
	

Value Representations:

		
			Decimal example: 66
Binary example: 100010b
Hex example: 42h
Register example: %ax
Bit of value example #1 (here is the 5 bit, here it will return 64): 42h$5
Bit of value example #2 (here is the 3 bit, here it will return 0): 42h$3
Bit of value example #3 (here is the 8 bit, here it will return 512): 10110001110b$8
		
	

Flags:

		
			Flags are stored in %flags
Bit 0 of %flags is %ax==0
Bit 1 of %flags is %ax>0
Bit 2 of %flags is %ax<0
Bit 3 of %flags is carry
