Section 21 Flash Memory
21.6
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 21.7 shows the errors and FLMSTR status and figure 21.6 shows a flowchart of full status
check processing and corrective actions for each error.

When H'FFxx is written in the second bus cycle of this command, the flash memory
enters the read array mode and the command code written in the first bus cycle is
ignored.
