18.4.5 Full Status Check
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 18.6 lists the Errors and FMR0 Register Status. Figure 18.14 shows the Full Status Check and
Handling Procedure for Each Error.

commands, at the same time the command code written in the first bus cycle will disabled.
