Table 45: Communication Timeout
It is possible to select the adaptive or the fixed timeout
in SSI mode. However in order to meet the require-
ments of the standard SSI protocol the fixed timeout of
20 µs should be chosen by setting NTOA to 1.
In SSI mode the sensor data can be output in binary or
Gray code.
SSI interface ring operation can be activated for the
repeated output of position data in SSI protocol. In this
mode position data output is repeated cycle by cycle
separated by a zero-bit until the internal timeout t_out (p.
12) is reached. After t_out has elapsed a new request can
be made for position data. By checking the repeated
position data for equality, SSI ring operation mode en-
ables any possible transmission errors to be detected.
If RSSI is deactivated zeros are subsequently output
after the position data output.
