Function
• Transfers n bits (words) between s and s + n − 1 to d + n − 1.
• The values between s and s + n − 1 are retained. However, if the transfer source and transfer destination ranges overlap, the
transferred values will be used.

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 transferred.
If n is a constant: 0 to 255 (decimal) can be designated for the number of bits (words) to be transferred.
Notes
• Use this instruction so that d + n − 1 and s + n − 1 do not exceed the I/O range (R7BF, M3FFF, WRFFF, and WM3FF). If
the I/O range is exceeded, DER is equal to '1' and the transfer is performed to the maximum range.
• If n is equal to “0,” the block transfer is not performed and DER (R7F4) will be set to “0.”
