Community Translation: AURIX™ MCU: PFLASHxの読み取り保護を有効/無効にする – KBA235238

Version: **

Enabling Read protection locks the debug interface. If Read protection is required but would require access to PFlash in the future, you should ensure that the code allows executing external commands (via LIN, UART, CAN, and so on) to perform the following PMU sequences:

  • Disable Protection
  • Resume Protection

For more details, see the following sections in the User’s Manual:

  • AURIX™ TC2xx devices: “Program Memory Unit (PMU)”  
  • AURIX™ TC3xx devices: “Non Volatile Memory (NVM) Subsystem” 

Note:

This KBA applies to the following series of AURIX™ MCUs:

  • AURIX™ TC2xx series
  • AURIX™ TC3xx series
