			execute a 16 bit ⋅16 bit multiplication between two indirect-addressed data memory
			buffers into a 32 bit accumulator. Circular buffer operation. Executes in 2 instruction
			cycles. Rx and R(x+1) automatically increments by 2 per tap.

1	0	CORK An, *Rx	Correlation function. When used with repeat will execute 16⋅16 multiplication
			between data memory and program memory, 48 bit accumulation, and a circular
			buffer operation. Each tap takes 3 instruction cycles. Rx automatically increments by
			2 per tap.

1	1	COR An, *Rx	Correlation function. When used with repeat will execute 16⋅16 multiplication
			between two indirectly addressed data memory buffers, 48 bit accumulation, and a
			circular buffer operation. Each tap takes 3 instruction cycles. Rx and R(x+1)
			automatically increments by 2 per tap.
