Note1) R: Read W: Write
2) Data register except specified is 0.
3) DT00061, 00062 (Unit for pulse output) is numerical value (in the range of data register).
4) If each setting value is wrote by communication, it memories to internal EEP-ROM at the same
time. Therefore, change setting frequently makes EEP-ROM’s life short. Avoid to usage like this.
5) Write a data within the range when you write it.
