Receive data update information
0：No update
Receive buffer (byte address 08h - 39h, word address 08h - 38h) contains the
same data as the previously read data.
(Received new data during the previous read, or the read interval is shorter
than the refresh cycle.)
1：Update
Newly received data is stored in the receive buffer.
(Even if the updated data is the same as the previously read data, if the receive
buffer has been updated this bit becomes "1".)
For an asynchronous read, ensure that this bit is set to "1" before reading the
receive data.
Send data write enable information
Enable
0：
Confirms that this bit is set to "0" and writes the send data into the update buffer.
Disable
1：
Writing to the update buffer is disabled when this bit is set to "1" because the
data is being transferred from the update buffer to the send buffer.
When the send data write completion flag (80h) is set to "1", the data transfer
from the update buffer to the send buffer starts and the status is set to disable.
When the transfer completes, the status is set to enable.
