- SSI Data word is a 32bit-wide data. Ch#0,1
- RUN : SSI Clock Output Enabled Flag
- WARN : Warning. Any warning has occurred, WFP, WSSIF or WSSID.
- DEC : SSI Data Decrement. It was set, it lasts until INC.
- INC : SSI Data Increment. It was set, it lasts DEC.
- WFP : Warning of Field Power (SSI Power).
- WSSIF : Warning of SSI Frame. The last bit of frame data is not trailed with 0.
- WSSID : Warning of SSI Data. SSI Data is 0 during gap of frames. Generally when invalid wiring or cross
wiring.

- RUN : SSI Clock Output Command, 1:Run, 0:Stop
- GRAY : Conversion Binary to Gray code. 1:Gray, 0:Binary (It has effect on Current SSI Data.)
- SSI Data Length : Sensor Resolution Bit + Sensor Number of turn Bit.
Example) Sensor Resolution (Step/Revolution)=8192 => 13bit, Sensor Number of turn=4092 => 12bit
SSI Data Length must be 25 (13bit + 12bit).
