T = Duration of clock signal,
min. 2 μSec = 500 kHz; max. 13 μSec = 77 kHz
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
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readout can be out of date and should be ignored.
