This register is used to write 1 words of data into the distributed address area in the internal data memory.
The data set in CR8 and CR9 (D15 to D0) is written into the address set in CR6 and CR7 (A15 to A0). When

The data at the address set in CR6 and CR7 (A15 to A0) can be read out into CR8 and CR9 (D15 to D0).
When this read-out is completed, this bit is cleared to “0” automatically. When reading out data successively,

Note:
1-word write control, 2-word write control and read control cannot be performed simultaneously to the internal
data memory. It is not allowed to set two or more bits of XDMWR, XDMRD and XDMWR2 to “1”
simultaneously.
