If an error occurs, bits FMR07 and FMR06 in the FMR0 register become 1, indicating the occurrence of an
error. Therefore, by checking these status bits (full status check), the execution result can be confirmed.
Table 26.6 lists error types and FMR0 register values. Figure 26.13 shows a flow chart of the full status check
and handling procedure for each error.
