How to access the Init buffer in PSI5 ASIC L9663? Can someone explain how to make use of init communication frame for reading the init buffer?

During the initialization process , the phase 2 data, the IDn and data blocks Dn of incoming sensor data is stored in "init buffer id (init_buf_id)" of the corresponding frame id at address n-1.

I need more details on how to make use of the communication frame for init data reading.

What does "init_buf_id" and register refer to in the following below image shown.

    Hello,

    in the image, "init_buf_id" identifies the init memory buffer which corresponds to frame control from incoming sensors data; "Register" is the address in which MCU can read init data content for the related memory buffer at the specified block ID .

    The storage is triggered only on demand through READ_INIT_DATAx bits in CHx_CR1 registers and SPI access can start after init_data_rdy is set.

    Regards,

    Pasquale
