5-23 Logic Instructions
5-23-1 COMPLEMENT – COM(29)
Limitations DM 6144 to DM 6655 cannot be used for Wd.
Description When the execution condition is OFF, COM(29) is not executed. When the
execution condition is ON, COM(29) clears all ON bits and sets all OFF bits in
Wd.
Precautions The complement of Wd will be calculated every cycle if the undifferentiated
form of COM(29) is used. Use the differentiated form (@COM(29)) or com-
bine COM(29) with DIFU(13) or DIFD(14) to calculate the complement just
once.
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.
5-23-2 LOGICAL AND – ANDW(34)
Limitations DM 6144 to DM 6655 cannot be used for R.
Description When the execution condition is OFF, ANDW(34) is not executed. When the
execution condition is ON, ANDW(34) logically AND’s the contents of I1 and I2
bit-by-bit and places the result in R.
