• The FMR07 bit (SR5) and FMR06 bit (SR4) are set to “0” by executing the clear status register command.
• When the FMR07 bit (SR5) or FMR06 bit (SR4) is set to "1", the program and block erase command are not accepted.

The status register indicates the operating status of the flash memory and whether or not erase or pro-
gram operation is successfully completed. The FMR00, FMR06, and FMR07 bits in the FMR0 register
indicate the status of the status register.
Table 18.6 lists the status register.
In EW mode 0, the status register can be read in the following cases:
The sequence status indicates the flash memory operating status. It is set to “0” (busy) while the auto-
program and auto-erase operation is being executed and “1” (ready) as soon as these operations are
completed. This bit indicates “0” (busy) in erase-suspend mode.
