Table 8. Exchanges EX and EXX
Block Transfer and Search
Table 9 lists the extremely powerful block transfer instructions. These
instructions operate with three registers.
•
•
•
After the programmer initializes these three registers, any of these four
instructions can be used. The
moves one byte from the location pointed to by HL to the location pointed
to by DE. Register pairs HL and DE are then automatically incremented
and are ready to point to the following locations. The byte counter
(register pair BC) is also decremented at this time. This instruction is
valuable when blocks of data must be moved but other types of
processing are required between each move. The
and Repeat) instruction is an extension of the
load and increment operation is repeated until the byte counter reaches the
count of zero. Thus, this single instruction can move any block of data
from one location to any other.
