When an error occurs, the FMR06 to FMR07 bits in the FMR0 register are set to “1”, indicating occur-
rence of each specific error. Therefore, execution results can be verified by checking these status bits
(full status check). Table 17.6 lists errors and FMR0 register status. Figure 17.12 shows a full status
check flowchart and the action to be taken when each error occurs.
