16.9. Slave Reset
On internal soft failures the Slave resets after 1 second or after an (error) frame is sent. On internal hard
failures the Slave resets itself. In that case, the Serial Protocol will not come up. The serial protocol link is
enabled only after the completion of the first synchronization (the Master deactivates /SS for at least t5).
16.10. Frame Layer
16.10.1. Command Device Mechanism
Before each transmission of a data frame, the Master should send a byte AAh to enable a frame transfer.
The latch point for the angle measurement is at the last clock before the first data frame byte.
16.10.2. Data Frame Structure
A data frame consists of 10 bytes:
The Master should send AAh (55h in case of inverting transistor) followed by 9 bytes FFh. The Slave will
answer with two bytes FFh followed by 4 data bytes and 4 bytes FFh.
16.10.3. Timing
There are no timing limits for frames: a frame transmission could be initiated at any time. There is no inter-
frame time defined.
