2021.1 English

The application error code is 32 bits long. For example, if the error code for PS is 0x8A05:

  • 0x8A indicates that a write error has occurred while writing RSA Authentication bit.
  • 0x05 indicates that write error is due to the write temperature out of range.

Applications have the following options on how to show error status. Both of these methods of conveying the status are implemented by default. However, UART is required to be present and initialized for status to be displayed through UART.

  • Send the error code through UART pins
  • Write the error code in the reboot status register
