XORD
The Exclusive OR Double is a 32 bit
instruction that performs an exclusive or
of the value in the accumulator and the
value (Aaaa), which is either two
consecutive V--memory locations or an 8
digit (max.) constant. The result resides
in the accumulator. Discrete status flags
indicate if the result of the Exclusive Or
Double is zero or a negative number (the
most significant bit is on).
Operand Data Type DL130 Range
A aaa
V--memory V All (See page 4--29)
Constant K 0--FFFFFFFF
Discrete Bit Flags Description
SP63 Will be on if the result in the accumulator is zero
SP70 Will be on is the result in the accumulator is negative
NOTE: The status flags are only valid until another instruction that uses the same
flags is executed.
In the following example, when X1 is on, the value in V2000 and V2001 will be loaded
into the accumulator using the Load Double instruction. The value in the
accumulator is exclusively ored with 36476A38 using the Exclusive Or Double
instruction. The value in the accumulator is output to V2010 and V2011 using the Out
Double instruction.
