In the below datasheet - https://www.nxp.com/docs/en/data-sheet/TJA1128-DS.pdf of TJA1128, I want to understand the below questions which is not available in google search.
My questions :
1. In Page 1, Section 2.2, It is mentioned as, "Quasi one-time configuration via Serial Peripheral Interface (SPI)" - What is the meaning of Quasi one-time configuration?
2. In the CONFIG mode, I am trying to load my configuration values from https://ww1.microchip.com/downloads/en/DeviceDoc/SAM_D21_DA1_Family_Data%20Sheet_DS40001882E.pdf this Microcontroller using SPI interface.
Question - I am sending a data, but the SBC LIN Device does not seem to respond at all? According to the Figure 3. - Does it mean that if the SBC LIN device is not responding to the configuration data, it is still present in the CONFIG state? If so, what might be the reason?
3. I was not able to find the RESET option or what happens to the RESET pin during CONFIG state and what happens to the RESET pin if the CONFIG state is not configured properly in the datasheet? Can someone help me?
