Rotary Position Sensor IC
16.8. Timing
To synchronize communication, the Master deactivates /SS high for at least t5 (1.5 ms). In this case, the
Slave will be ready to receive a new frame. The Master can re-synchronize at any time, even in the middle
of a byte transfer.
Note: Any time shorter than t5 leads to an undefined frame state, because the Slave may or may not
have seen /SS inactive.

Remarks
No capacitive load on MISO.
t1 is the minimum clock period for any
bits within a byte.
t2 the minimum time between any other
byte
Time between last clock and
/SS=high=chip de-selection
Minimum /SS = Hi time where it’s
guaranteed that a frame re-
synchronizations will be started.
Maximum /SS = Hi time where it’s
guaranteed that NO frame re-
synchronizations will be started.
The time t6 defines the minimum time
between /SS = Lo and the first clock edge
t7 is the minimum time between the
StartByte and the Byte0
Maximum time between /SS = Hi and
MISO Bus High-Impedance
Minimum time between reset-inactive
and any master signal change
