is greater than 32, SSI communications are disabled and an SSI Data Setting Error event
occurs.

The following tab page is displayed.
2 Set the Leading Bits parameter.
A parity check is performed on all bits after the bits of SSI data are shifted.
If a parity error is detected, it is reflected in the error code in the SSI Status parameter.
