16.4.2.7. Fatal Bus Error Scenarios

A fatal bus error occurs when the master interface issues an error response. This error is a system error, so the software driver must not perform any further setup on the controller. The only recovery mechanism from such scenarios is to perform one of the following tasks:
  • Issue a reset to the controller through the reset manager.
  • Issue a program controller reset by writing to the controller reset bit (controller_reset) of the ctrl register.
