R4L–1 → R4L
Until R4L = 0
else next;
EEPMOV.W —
if R4 ≠ 0 then
Repeat @ER5+ → @ER6+
R4–1 → R4
Until R4 = 0
else next;
Transfers a data block according to parameters set in
general registers R4L or R4, ER5, and ER6.
R4L or R4: size of block (bytes)
ER5: starting source address
ER6: starting destination address
Execution of the next instruction begins as soon as the
transfer is completed.
Notes: 1. Size refers to the operand size.
B: Byte
W: Word
L: Longword
