Description
Standard SSI, no error-bit
Standard SSI, error-bit low active
Standard SSI, error-bit high active
extended SSI, data-package like BiSS-C
Table 44: MODEA: SSI
In standard SSI mode singleturn data and, optionally,
multiturn data, an error, and a stop zero can be transmit-
ted. In extended SSI mode (ExtSSI) the multiturn data
(optional), singleturn data, error, warning, and CRC can
be read out. All data is sent with the MSB first and is
equivalent to the data package that is output through
BiSS.
The SSI interface of iC-MU150 can handle sensor data
communication and unidirectional register communica-
tion (Advanced SSI protocol see Figure 17).
