No parity
In normal serial communications, data is configured in single bytes, and messages are
created by stringing together multiple bytes of data. The parity check described here
sets the check for each byte of data. Set the parity check method that is required by the
Master.
Note
The entire message is checked by a separate check code called “CRC-16,” so the
communications data will be checked even if no special parity check is performed.

Send Wait Time Setting (n156)
