4.14.54 ORS			Bitwise OR String
Syntax
	[label]	name			dest, src [, src1]									Clock, clk			Word, w			With RPT, clk							Class
		ORS			An, {adrs}										Table 4–46					Table 4–46								1b
		ORS			An[~], An[~], pma16										nS+4			2				N/R						2b
		ORS			An[~], An~, An										nS+2			1			nR+2							3
Execution			dest		⇐	dest		OR		src		(for two operands)
			dest		⇐	src1		OR		src		(for three operands)
			C ⇐ PC + w
Flags Affected			dest is An:									OF, SF, ZF, CF are set accordingly
			src is {adrs}:									TAG bit is set accordingly

Description			Bitwise OR of src and dest. Result is stored in dest. If three operands are
			specified then logical OR src1 and src, store result in dest.
Syntax						Description
ORS An, {adrs}						OR RAM string to An string
ORS An[~], An[~], pma16						OR ROM string to An[~] string, store result in An[~] string
ORS An[~], An~, An						OR An string to An~ string, store result in An[~] string

Example 4.14.54.1			ORS A0, *R2

OR data memory string beginning at address in R2 to accumulator string A0. Result stored in accumulator string A0.

Example 4.14.54.2 ORS A0, A0~, 0x13F0

OR program memory string beginning at address in 0x13F0 to accumulator string A0~, put result in accumulator string A0. Note that the address 0x13F2 is a program memory address.

Example 4.14.54.3 ORS A0, A0~, A0

OR accumulator string A0 to accumulator string A0~, put result in accumulator string A0.
