Chapter 5: Standard RLL Instructions - Logical
Exclusive Or Double (XORD)
1
The Exclusive Or Double is a 32-bit instruction that
230
performs an exclusive OR of the value in the
240
accumulator and the value (Kaaa), which is an
2
250-1
8-digit (max.) constant. The result resides in the
260
accumulator. Discrete status flags indicate if the
3
result of the Exclusive Or Double is zero or a
negative number (the most significant bit is on).
