[1]

The mechanical angle step is not synchronized with the SENT frame. Thus the worst case settling time is extended with the length of a complete SENT

frame.

[2]

Refers to analog output; additional information including times for digital output is provided in the safety manual.

[3]

SENT update rate at Tclk = 3 µs, 6 DATA nibbles, and no PAUSE pulse.

[4]

12 bit fast mode.
