4.37.2. Description

As long as the Ignition signal is present, the SBC is operating normally in Running mode. If the Ignition signal is removed, the MCU will request to send the SBC to Standby mode. If no Ignition signal is present in Standby mode, the SBC will power down and also stop powering the MCU, which will then also shut down. When the Ignition signal is detected again at the SBC, it will start up and power the MCU. The MCU will then initialize the SBC, which will return to normal operation in Running mode after the initialization is complete. This sequence is shown in Fig. 4.18.

4.37.3. FAQs

Question:

The MC33FS830A0ES needs to be programmed. Can the programming procedure for NXP MC33FS8530A0ES be shared?

Answer:

Unfortunately not. The details of how to program the MC33FS830A0ES cannot be shared due to NDAs. You need to get in contact with the manufacturer for this information.
