FMR0 Register (Status
When an error occurs, the FMR06 to FMR07 bits in the FMR0 register are set to 1, indicating occurrence of
each specific error. Therefore, checking these status bits (full status check) can determine the executed result.
Table 19.6 lists the Errors and FMR0 Register Status. Figure 19.16 shows the Full Status Check and Handling
Procedure for Individual Errors.
