The status register indicates the operating status of the flash memory and whether an erasing or a pro-
gramming operates normally and an error ends. The FMR00, FMR06, and FMR07 bits in the FMR0
register indicate the status of the status register.
Table 17.8.1 shows the status register.
In EW0 mode, the status register can be read in the following cases:

The sequence status indicates the operating status of the flash memory. This bit is set to “0” (busy)
during an auto-programming and auto-erasing and “1” (ready) as soon as these operations are com-
pleted. This bit indicates “0” (busy) in erase-suspend mode.
