If an error occurs, the FMR06 to FMR07 bits in the FMR0 register are set to “1”, indicating a specific error.
Therefore, execution results can be comfirmed by verifying these status bits (full status check).
Table 18.7 lists errors and FMR0 register state. Figure 18.15 shows a flow chart of the full status check
and handling procedure for each error.
