4.14.87 XORS			Logical XOR String
Syntax
	[label]	name		dest, src [, src1]	Clock, clk	Word, w		With RPT, clk	Class
		XORS		An, {adrs}	Table 4–46			Table 4–46	1b
		XORS		An[~], An[~], pma16	nS+4		2	N/R	2b
		XORS		An[~], An~, An	nS+3		1	nR+3	3

Execution	dest ⇐		dest	XOR src						(for two operands)
	dest ⇐		src1	XOR		src				(for three operands)
	PC ⇐ PC + w
Flags Affected	dest is An:							OF, SF, ZF, CF are set accordingly
	src is {adrs}:							TAG bit is set accordingly

Description	Bitwise XOR of src string and dest string. Result is stored in dest string. If three
	operands are specified, then logical XOR src string and src1 string, store result
	in dest string.
Syntax			Description
XORS An, {adrs}			XOR data memory string to An string
XORS An[~], An[~], pma16			XOR program memory string to An[~] string, store result in An[~] string
XORS An[~], An~, An			XOR An string to An~ string, store result in An[~] string

Example 4.14.87.1	XORS A0, A0~, *R2

XOR data memory string beginning at address in R2 to accumulator string A0~, put result in accumulator string A0.

Example 4.14.87.2 XORS A3~, A3, *R1++R5

XOR data memory string beginning at address in R1 to accumulator string A3, put result in accumulator string A3~. Add value in R5 to the value in R1 and store result in R1.

Example 4.14.87.3 XORS A1~, A1, 0x100 * 2

XOR program memory string beginning at word address 0x0100 to accumulator string A1, put result in accumulator string A1~.

Example 4.14.87.4 XORS A2, A2~, A2

XOR accumulator string A2 with accumulator string A2~ string, put result in accumulator string A2.
