5-23-4 EXCLUSIVE OR – XORW(36)
Limitations DM 6144 to DM 6655 cannot be used for R.
Description When the execution condition is OFF, XORW(36) is not executed. When the
execution condition is ON, XORW(36) exclusively OR’s the contents of I1 and
I2 bit-by-bit and places the result in R.
Example
Flags ER: Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
EQ: ON when the result is 0.
5-23-5 EXCLUSIVE NOR – XNRW(37)
Limitations DM 6144 to DM 6655 cannot be used for R.
