Table 21.6 Errors and FMR0 Register Status
NOTES:
FMR07 Bit FMR06 Bit
21.3.8 Full Status Check
(SR5)
(Status Register)
If an error occurs when a program or erase operation is completed, the FMR06, FMR07 bits in the FMR0
register are set to 1, indicating a specific error. Therefore, execution results can be confirmed by checking
these bits (full status check).
Table 21.6 lists the Errors and FMR0 Register Status. Figure 21.12 shows a flow chart of the Full Status
Check and Handling Procedure for Each Error.
1. The flash memory enters read array mode by writing command code xxFFh in the second bus cycle of
2. When the FMR02 bit in the FMR0 register is set to 1 (lock bit disabled), no error occurs even under the
