• The value of s (bit, word) is copied from d to d + n - 1.
• The value of s is retained.
• A bit is copied to bits and a word is copied to words.

n bits (words)
If n is a word:
The contents (0 to 255) of the lower 8 bits (b7 to b0) of n (WX, WY, WR, WM, TC) are set to the
number of bits (words) to be copied.
If n is a constant:
0 to 255 (decimal) can be designated for the number of bits (words) to be copied.
Notes
• Use this instruction so that d + n - 1 does not exceed the I/O range (R7BF, M3FFF, WRFFF, and WM3FF). If it exceeds the
I/O range, DER is equal to '1' and transfers to the maximum range.
• If n is equal to “0,” the block copy is not be performed and DER (R7F4) will be set to “0.”
