																			CHAPTER 4: INSTRUCTION SET
SUB [%ir],%r				Subtract r reg. from location [ir reg.]																2 cycles
Function: [ir] ←		[ir] - r
	Subtracts the content of the r register (A or B) from the data memory addressed by the ir
	register (X or Y).

operation: SUB		[%X],%r			[00imm8] ←					[00imm8] - r (00imm8 = 0000H + 00H to FFH)
	LDB	%EXT,imm8
	SUB	[%Y],%r			[FFimm8] ←					[FFimm8] - r (FFimm8 = FF00H + 00H to FFH)

SUB [%ir]+,%r					Subtract r reg. from location [ir reg.] and increment ir reg.																	2 cycles
Function: [ir] ←		[ir] - r, ir ←			ir + 1
	Subtracts the content of the r register (A or B) from the data memory addressed by the ir
	register (X or Y). Then increments the ir register (X or Y). The flags change due to the operation
	result of the data memory and the increment result of the ir register does not affect the flags.
