Data SSI
Gn Gn-1
Attention: With SSI compatible transmission data are
updated synchronous with the readout cycle. The data are
as up to date as the time interval between two readouts.
A periodical readout is therefore recommended. After a
longer readout break the data contents of the first readout
can be "out of date" and should be ignored.

Parameters are stored
T = Duration of clock signal,
minimum 2 µSec = 500 kHz,
max. 13 µSec = 77kHz
Tv = Delay time max. 360 ns
Tm = Minimum time between last rising edge
and reloading of SSI approx. 24 µSec.
Gn = MSB (here Gray Code)
24 bit transmission:
G1 = second LSB, G0 = LSB
24+E transmission: G1 = LSB. G0 = Error bit
25 bit transmission: G1 second LSB, G0 = LSB
