Function
When the input is ON, data block transfer is performed between the source which is indirectly designated by
A
and
A+1
and the destination which is indirectly designated by
C
and
C+1
. The transfer size (number of
words) is designated by
B
.
The transfer size is 1 to 256 words. (except for writing into EEPROM)
