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 combine
COM(29) with DIFU(13) or DIFD(14) to calculate the complement just once.

DM 6144 to DM 6655 cannot be used for R.
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.
