27 / 184 page  4.2.4 SPI protocol details The protocol is out-of-frame in order to manage the propagation delay of the commands sent by MCU and the answers generated by the L9963E stacked in the vertical interface. A command sent at the N-th frame will receive its feedback at the (N+1)th frame. Figure 11. Out of frame protocol description MCU can access the devices in different ways. 4.2.4.1 Single access The single access behavior is based on a Write and Read approach. The execution of each WRITE command sent by MCU can be immediately verified by interpreting the answer incoming from the addressed device. Any reply is buffered into L9963E Master unit, which passes it to the MCU on its next command. Figure 12. Write and read access Table 19. SPI protocol: single access addressed frame (write and read) Dev ID Address DATA WRITE CRC Dev ID Address feedback DATA READ CRC READ commands require the same inter-frame time as the WRITE ones. Any reply is buffered into L9963E Master unit, which passes it to the MCU on its next command. L9963E Serial communication interface DS13636 - Rev 12 page 27/184 |
