Section 23 Flash Memory
23.9
When an error occurs, the FMERSF or FMPRSF bit in FLMSTR becomes 1 to indicate
occurrence of the error. Read these status bits (full status check) to check the operation results.
Table 23.8 shows the errors and FLMSTR status and figure 23.8 shows a flowchart of full status
check processing and corrective actions for each error.
