Exclusive OR Formatted (XORF)
The Exclusive Or Formatted instruction performs an exclusive OR
230
of the binary value in the accumulator and a specified range of
discrete memory bits (1 to 32).
240
250-1
The instruction requires a starting location (Aaaa) and the number
of bits (Kbbb) to be exclusive ORed. Discrete status flags indicate if
260
the result of the Exclusive Or Formatted is zero or negative (the most
significant bit is on).

NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the binary pattern of C10–C13 (4 bits) will be
loaded into the accumulator using the Load Formatted instruction. The value in the
accumulator will be logically Exclusive Ored with the bit pattern from Y20–Y23 using the
Exclusive Or Formatted instruction. The value in the lower 4 bits of the accumulator are
output to C20–C23 using the Out Formatted instruction.
