(2) If is a bit device, only the lower 32 bits of the multiplication result will be considered, and the
D
upper 32 bits cannot be designated.
Example K1........... Lower 4 bits (b0 to 3)
If the upper 32 bits of the bit device are required for the result of the multiplication operation,
first temporarily store the data in a word device, then transfer the word device data to the bit
device by designating (
(3) The values for
32 bits).
